Usually, the larger the diameter, the more powerful the spring.
Using the laylax springs... usually 200sp+ springs are 9mm diameter
and -200sp.
Although that's not always the case.

There's laylax and DPI... Don't know which one to choose... From the look on classified, people usually mix the two... Is that a good idea?...

It doesn't really matter, although I prefer laylax, just remember to use parts of the same manufacturer, most importantly your cylinder assembly and trigger.
Although mixing a pdi barrel or hopup chamber with laylax cylinder internals won't matter...

Also, does TM v/zero trigger fit a maruzen clone?

The zero trigger is made by laylax, the v made by pdi, they should fit, if not, all they need is a little modding... but well worth the 10 minutes

Good luck
