I think our Matt has done some SOTA judging by his past videos and CTX status here. I'm sure several others have too.
In my past I was a walker so simple lightweight bivvy stuff, so no real idea on 'luxurious' camping
The tent you're looking at seems to be ideal for the price and I've seen SOTA activations in smaller tents. Might be just the job, but you don't gain real knowledge with it until you actually try. Someone's bound to have some input though.
Avoid or consider? Hmmm, be careful you don't empty your bank account on recommendations!
Honestly, go on a SOTA site and they'll having you lashing out for Force 10s and stuff!! It's a SOTA, not Everest base camp!
Anyway, hope you get some useful pointers.
All the best,
