Iron choice isn't about marketing. It's about what fabric you're actually dealing with.
I've gone through probably a dozen irons over the years, from cheap ones you buy at the supermarket to the kind that costs as much as a small appliance. The honest answer to qual o melhor ferro de passar roupa depends on how much laundry you do and what kind of mistakes you're willing to make. Most people buy the wrong iron because they focus on wattage, which is mostly meaningless for steam output.
What actually matters when you pick one
Steam output measured in grams per minute is the real number. Look for at least 40 g/min for continuous steam if you have a lot of cottons and linens. Burst steam around 120 g/min helps get wrinkles out of thicker fabrics in one pass. A ceramic or stainless steel soleplate with good heat distribution matters more than the brand name. Ceramic spreads heat evenly; stainless steel is durable but can stick on delicate synthetics if you press too hard. I ended up buying a Bosch TDS 7542 because the specs looked reasonable and the price was mid-range. It has a 2600W heating element, 50 g/min continuous steam, and a ceramic soleplate with laser-cut steam holes. After six months of weekly use, it still performs fine. The anti-calc system keeps mineral buildup manageable if you use tap water. If you live in an area with very hard water, distilled or demineralized water will extend the life of the iron significantly.
The problem I ran into and how I fixed it
About four months in, the iron started leaving brownish streaks on dark shirts. I thought the soleplate coating was wearing off, but it was actually calc deposit being pushed out through the steam vents. The self-clean cycle on that model is supposed to handle this, but I was only running it once a month instead of once a week. I switched to weekly self-cleans and switched to a mix of half distilled water for the tank. The streaks stopped completely. That's a maintenance issue, not a product defect, but most people never figure that out. Another thing nobody tells you: don't fill the water tank above the max line. Overfilling causes dripping during use, which defeats the purpose of a dry iron session. I learned that the hard way on a batch of linen tablecloths.

Specific recommendations based on actual use
If you iron frequently and deal with heavy fabrics like denim and linen, go with a high-steam corded iron. Cordless models are convenient but the smaller water tanks and lower power output mean you'll spend more time going back to the base. For light occasional use, a compact iron is fine. Philips GC series and Tefal Pro Express are reliable workhorses. The Tefal FV9850 has 55 g/min continuous steam and a self-cleaning anti-calc system, which handles most household needs. Avoid the cheapest irons under R$100. The soleplates on those are thin, heat distribution is uneven, and the thermostat isn't calibrated well. You'll get scorch marks on silk and still have wrinkles in cotton. That's not worth the savings.
Counter-intuitive things to know
Higher wattage does not equal better ironing. A 2000W iron heats up fast but may not sustain steam pressure as well as a 2400W model with a larger boiler. Wattage is about how quickly the element reheats between bursts, not how much steam it produces. The steam generation system is what matters. Also, ironing on the highest setting doesn't remove wrinkles faster. It burns fabrics. Cotton can handle high heat, but synthetic blends need medium. Always check the garment label first. Another common mistake: people iron dry cotton shirts at high heat without any steam. That's inefficient. Adding steam lets the fibers relax at lower temperatures, which removes wrinkles faster and reduces scorch risk. I cut my ironing time from about 45 minutes to roughly 20 minutes per load just by using steam consistently and adjusting temperature per fabric type.
If you have a lot of delicate fabrics, consider a steam generator iron instead of a standard one. They have a separate water reservoir and produce much higher steam volume. The upfront cost is higher, maybe R$600 to R$1200, but if you iron daily, it pays for itself in time saved and fewer ruined garments. The Rowenta DW9260 is a solid option in that category, with about 200 g/min burst steam and a large 1.7L water tank.
Bottom line without the sales pitch
For most people, a mid-range corded iron with at least 45 g/min continuous steam and a ceramic soleplate is the right call. Clean it weekly, use the right water for your area, and adjust temperature by fabric. That's it. No need for fancy features you'll never use. The best iron is the one you'll actually maintain properly, because even an expensive one will fail fast if you ignore descaling.
