I don't know b1 so I can't comment which is better.
Not a bad map. Looks a little bit complex, so needs 2 adequate teams to have a fun match. Nothing wrong with that I guess.
I for one didn't like the ice jump up the ramp through some tiny cap, I also didn't like the brightness. It especially felt 'off' when sun was directly to grass. Tha and the combination of light walls made the strain to the eyes quite obvious. I think I'm using default everything (textures, brightness, etc), so maybe there's a gap there?
There is a bug on the wall. Ice, next to the ramp on the blue side (the ramp to grass).
There is a bug on the high base or whatever. Where there is a gap on the wall. You can jump there and can get stuck.
I can provide ss's if you don't get what I mean.
There is a bug with some of the spawns - facing walls.
The gap on the base wall - can fall into that and get stuck.
All those models you added were a nice touch, except for the rope thingie, didn't quite get that
Bases. Base is huge, good visibility, lots of entrances. But at the same time the flag looks quite 'random'. If you manage to take the flag, you can take a fast exit to ice, up the rope, or to mid. If the enemy was camping and you succeed, then I think you get an easy capture. But I have a feeling most of the time it gets down to aggresive team constantly being killed by the base camper, because it's quite simple to defend the flag. But this is all just a guess, need to play on it to suggest how the flag should be located.
I don't like the 'jumppad barrel'.
Since the routes in this map aren't really super-connected it is easy to reach enemy base without even seeing the enemy once. It's fine to happen sometimes, but this makes this map more of a racing map - a contest who can capture the most flags. Can't say for certain that this is the case, but it sure looks like it. Of course, this doesn't look as bad as tatras/prolandr or something
