I've been making my own marshmallow fondant, but am thinking about switching over to commercial to save time and it also seems easier to work with/tears less.  People, however, really like the taste of my marshmallow fondant and I don't really want to put fondant on a cake only for people to tear it off when they eat it.  Is there any good tasting commercial fondant that is comparable to marshmallow fondant?

This is like asking, "Is Pepsi better than Coca Cola"?  You'll get a thousand different answers, all of them "right".  The only way you can find this out is to try them yourself and see what you think.  It is possible to get sample packs of commercial fondant at a minimal cost (do an online search). 

Just like everything else with food, everybody has a different opinion of  what is "good".  From reading hundreds of threads (and trying lots of different commercial fondants), the general consensus is that homemade fondant is generally much tastier than commercial.   However, commercial is more consistent and may be more profitable since less prep time is involved. 

It does save time, that's for sure. Personally the only commercial fondant I would use is any of the Swiss types. Carma, what Albert Uster sells, etc. They truly do taste good, but costly, so I make my version of MFF and life goes on. Everything else stinks to me. :(

I don't have a huge problem making fondant.  I just had to buy some chocolate fondant for a last minute cake and it was so easy to work with, I was amazed.  My marshmallow fondant is fine, but seems to tear a lot easier than the store bought.

I never make my own fondant as I find that the comical brands are so much better to work with and I actually like the taste! The fondant I use is Satin Ice, it's consistent and I find it gives the best result.

I use Carma's, I really like the taste, not sickly sweet or chemically like a lot of the other commercially made brands.

I personally hate MMF, I will make it once in a while when a bride really wants it, but I usually give them a sample of each and they choose Carma's. I don't find it difficult to work with, I just think it's over the top sweet.

That said, Apti is right, everyone's opinions will be different, I agree with the idea of getting samples.

I've tried the Fondarifc and Finishing Touch brands. They both taste good, and I believe the Fondarific has different flavours consistent with the different colours. I've yet to try Satin Ice. (And actually, I still make my fondant, and mix in a bit of the commercial stuff to help with the texture when I need to Fondant is NOT inexpensive where I am)
 

I don't like MMF either.  I usually use SatinIce or PettinIce.

I make my own fondant, but not marshmallow fondant. You might try a traditional recipe that doesn't use marshmallows to see if you like it better.

Where do I look for samples?

do a google search for "fondant samples"

Here are some results:
