I have done both.
I feel it is pretty similar to be honest.
It depends how you train I think. Like I see some people that try to pre-empt every eventuality they think they will face. And so really over emphasise the street sport difference. Wearing shoes or fighting in the dark or whatever.
I don't I deal mostly in concepts. So it is much of a muchness.
There are a few tricks or traps that might be environment specific. I hit kasegetami to avoid scraping my knees for example.
But the bulk of what works. Works everywhere. Especially if I am not getting in fights all the time.
The Martian "do the math" speach is the best example for this idea.
Training to win. You just change the objective. If I am on the ground. I can win by getting off the ground. I win by getting that underhook. That let's me get off the ground.
It is all broken down in to these little puzzles and competitions.
