I dunno about benefiting your form. Are these the same style of TCC, or different?
As I said, it's up to you who you train with.
Now, understand that there can be problems training too many differing styles at once.
Each style emphasizes a different aspect of TCC. Each Master has a different viewpoint on which aspects of TCC should be more prevelant in their forms.
Your overall training will likely be enhanced, IF you have your forms down allready in your fist style and are the kind of person who can easily assimilate another form.
I happen to know five differing hand forms, of differing lengths, of different styles, each which emphasizes a different aspect. I know them all well, though I'd have to say the segmented, or square, form of the Wu family is the one I'm the most familiar with. Three are from the Wu tradition, three from the Yang tradition. I also know many different variations on each and every one of these forms.
I won't even go into weapons forms, sheesh, too many.
I honestly believe that each form I've learned has helped out, overall, with my TCC in general. I see new things, find different applications because each form does the same move slightly differently but I can then go back to the other form and say, "Aha! I see it now" or sometimes I stand there saying, "What the he...."
But in the long run, I believe my TCC has improved slightly from each.
Now, if you are new to training, or you aren't the kind of person who can easily assimilate many different forms, then you will not be best served to train with a lot of people until you get to the point where the one you were learning before is allready well known to you.
Be careful with this power you have to make the decision. Don't be too hasty, don't jump into the trap of "teacher shopping" in the hopes that one Master will teach you more, better or faster.
Odds are, they are only going to teach you "different" and that's doesn't always equal more, better or faster.
That said, it's still up to you.
Have fun, that's all that really matters in the long run anyway.
