Really depends on location. A Yaris in Japan is still a true Yaris, where as a Yaris in the US is a rebadge Mazda 2 and in Europe, the Mazda 2 hybrid is a rebadged Yaris hybrid.

I can vouch. Owned 6 Mazdas from the 3 to the 6. Reliable vehicles. My parents, my sister and her husband and I switched from early 90s Toyotas to mid 2010s Mazdas. Now we’re just all over the place with brands. I’m back in Toyota product, Lexus GS currently. I had 4 other Lexus after my Mazda. I really do miss my 6 though. Great quality, very good fit and finish and a reliable powertrain that isn’t a ford influence. Soft touch panels everywhere in the 6. I sat in a Camry and it’s hard touch plastic throughout.

Depends on location. Japanese and European Yaris is a Yaris, no rebadge. US marketed is a rebadged Mazda 2
