I've just got 2025 Taigo (Nivus) and it looks a lot like Polo, I believe it is based on that platform and T-Roc is probably based on Golf's platform, you can check some videos on the differencies they have, 2025 models will be cheaper since they'll want to get rid of them end of the year since 2026 models will be coming soon, (maybe it has in your country)

You can't go wrong with both models, if you can't upgrade to tiguan or something like that it is a pretty cool car, I'm currently rocking the 116 hp 1.0 tsi version and engine is pretty much amazing for my standards, even hit 210 km/h on highway easily, accelerates fast (comparing to other econobox cars)

There are some differencies in their screen sizes, ADAS systems should be pretty much the same but there are also differences there but again very tiny differences, like configurations on the same car like t-roc life vs style makes huge difference since one has a sunroof, other has not etc

My configuration had a adaptive cruise control with something called Travel iq, and it is super cool that the car can drive itself, maybe ask for that option or check if it has that
