Hopefully this isn't off-topic. I own the ETS125. It seems to be great for sanding bare wood in prep for finishing. If I'm looking for a sander that could be more aggressive when trying to level our small imperfections and smoothing out small differences on the surface on glued joints, what would be the best sander for this. I don't need a sander which takes off a ton of material. I try to avoid that when gluing and there are other tools I have which would be better for that job. Would that be an ETS150 (3 or 5)? Or would the Rotex 125 or 150 be better? (125 for sure if the same paper can be used as for the ETS125). I don't really need an "aggressive" sander.
While the RO125 would match your existing paper, it's heavier than the 6"/150mm ETS models and more tiring to sand with for long periods of time with just 1 hand IMO.
Either ETS can be gentle depending on the grit of abrasive and type used, plus technique, but the 150/5 will sand faster since it's about twice the orbit of your ETS 125 versus the 150/3.
