I assume not all softboards are born equal.

I'm a beginner trying to become a intermediate and I'm trying to get some advice on a "better" softboard to get.
So far I got the ones from Decathlon (old Tribord 100) 8" board no issue with size don't mind at all to keep using this size, what I mind is that
the board feels like a sponge absorbing water. Have two and both have now big bumps in them, one on the top the other on the bottom side. (can share photos if you'd like to laugh a bit)
Now I can get again newer from Decathlon, seems their newer models are a bit better still I see many comments about it sucking a lot of water and not performing very well.
So asking here for some advice on other brands models of softboard to get (in 7'' to 8'' range). Something that is more well built and that will
perform a bit better in the water. I saw the ones from catch surf but they are stupidly expensive to get here.
Thanks
