Welcome Fozzy

You don’t work for KMS by any chance do you?

As sjv says, APR or REVO have a good dealer network and aftercare support too.
I’ve had a few REVO maps in the past which were very good, I’ve yet to try APR.
There haven’t been any back to back comparison mk7.5 GTI remap threads here that I remember. Different maps on different rolling roads on different days will give different results. Looking at the graphs supplied by the tuning companies will give an idea but there’s a lot more to it than that. What looks great in 2D graphs might not be so good on the road, especially when you’re not driving flat out.
Going to a good local dealer is always recommended and therefore you already have your answer.
There is much more tuning discussion on Golf R’s as they’re more tune friendly (more turbo headroom and no traction issues) but so long as you don’t expect it to rev into the stratosphere and focus more on mid range punch then you’ll have a very fast real world car with a stage 1 GTI.
I’m sure you’ll get some good feedback here from people that have had one map or another but very few will have tried more than one unless they have a friend with a different map.
You’re not going to go far wrong with APR that’s for sure.
