Not quite sure what you're trying to say here. If you've only heard it, then it isn't really your "experience", is it? Your phrase would mean something like "hearing from my experience", which doesn't really make sense. Better to go with
(私が)聞いた話では
聞いた話によると
...or the like. ("According to what I heard...")
This would sound better as:
私の経験から言えば、日本語を勉強することが楽しいです。
・・・日本語を勉強するのが楽しいです。
・・・日本語の勉強が楽しいです。
What exactly are you trying to say here? Without any additional qualifiers, 最高の雪 would mean something like "the best snow" (as in, the best snow for skiing or snowboarding).
In any event, the particle you have after 雪 is wrong, and 降るのがあります doesn't really make sense.
I could give you an answer based upon one possible interpretation, but maybe clarify what you're trying to say and try again yourself. Not to discourage you, but you seem to be confused about basic particles and grammatical constructions. I would suggest you go back and review those, as being able to say "In my experience..." isn't particularly helpful unless you can meaningfully describe what that experience is.
