I really can't say. I would say the appeal of BG3 is very, very different than that of Infinity Engine games and Tim Cain's RPGs - their focus and priorities are just in different places.
But if the combat is what you are worried about, I wouldn't. If you suffered through Fallout1&2 just fine, than BG3 shouldn't scare you.
D:OS1&2 are closes counterparts to BG3, but in my opinion BG3 is superior in quite a few aspects. While I have issues with BG3 narrative, it is stronger than in previous titles giving players more direction. I did feel D:OS1&2 had a lot of aimless exploration while looking for something interesting to happen. D:OS2 act2 was an extreme drag, and BG3 has nothing close to that. I also feel combat in BG3 is a bit more sporadic - or at the very least it's combat offers quite a bit more variety, while D:OS2 armor system made everything feel homogeneous.
So, yeah. I can't promise that you will click with BG3, but I think it would be worth giving a shot.
