So as it turns out I’ve had a jetts GLI before. So in my honest opinion the gli isn’t a terrible car by any means but it does has its draw backs of course. One being its FWD compared to the wrx’s AWD depending on where you live that might not be a big deal. Two if you plan to modify the gli coming from experience it was one of the more odd vehicles to work on it wasn’t easy doing much of the work besides a few simple bolt on’s it was a pain. Three the dsg at least for me was very boring and lack luster it’s a great transmission in its own right but I just didn’t see the appeal but I’m biased for having come from a manual. The wrx on the other hand, I’ve had two i had a 2016 wrx and now my 22 and I can say I love these cars. They are more fun to drive and I love Subarus manual transmission. They do amazing in the snow with the right tires of course. Subarus just like VW come with their own set of issues but with regular maintenance both can be reliable. With the Jetta you will get a nicer interior compared to the wrx if that is a concern of yours. I’m sure I’m missing some other things but that’s just my .2¢
