I love the OPI nail polish shade Lincoln Park after Dark, so I grabbed it in both the OPI Suede version (read my OPI Suede Lincoln Park After Dark review) and the Matte version. OPI says that because the suede and matte polishes do not wear as long to not use a base coat with them. Trust them on that! When I tested OPI Suede, I followed that advice and it wore very well. I forgot when I tried the OPI matte and it was chipping off less than 24 hours after I put it on! Not using a top coat it obvious--it would ruin the mattte or sude look.
In terms of appearance, I like the Lincoln Park After Dark matte version better than the suede. But I still prefer the regular polish over both of them. If you try the matte, experiment with doing a glossy tip. I think that gives the matte nail polish looks a better overall look. I also like using a mattifying top coat better than using the already matte nail polishes. It seems to wear longer and gives more flexibility, since you can wear your favorite polish shades either normally or matte that way.
