Thumpy, chewy and old school! Arguably more so than Flatwounds, but they certainly live in the same tonal ballpark. The main difference for me is the way they interact with the frets - tapes have a rubbery/plasticky “clack” whereas flats have more metallic “clank”. Ultimately though, in a mix, they’ll sound similar enough to not make much difference. The main deciding factor for you will be whether you like looser feel of tapes vs the stiffer feel of most flats.
The video below shows the sound differences pretty well IMO:
