You can get a Weller in the 120W and higher but I have yet to find the need for anything that big. Plus, it drives the price up too. It's all about what you want, how much you want to spend, tip availability and cost etc... Some guys are Brand Whores, some not. When you list out what you want, the cost of tips and pencils, a replacement element and compare costs and reviews, you'll find what you are looking for.
Never heard of a Pace AD5200 (Maybe a ADS200) but the Weller will solder the 40 amp BR's and everything else asked of it. Not everyone has the money for Hot Air Rework (plenty of free hot air here).
Here goes the "Dick Measuring Contest" Mine is bigger, mine is hotter, mine is longer............ Screw that. If you are working on amps and such, 80 Watts is fine no matter what brand you decide on.
