You can surely mix with that bundle, no doubts. Overall you don't really need anything else; that bundle pretty much covers it all. But if you ask if there is anything better? Hmh.. I wonder if you are asking only for the plugs or some outboard too? No plugs can really beat outboard yet, especially not verbs (those impulse verbs do sound quite nice thou).
Some of the nicest plugins I know are UAD plugs (thou they don't work with the Pro Tools I think..?). Also definitely check
the Sonalksis SV-517 EQ, very good one. And also the Tritone Digital's EQ series is reeeeally good (
HydraTone and ValveTone´62 and...).
I think WAVES has quite nice compressors (C1, C4, Rcomp, RVox; very usable all). Also L1, and L2 and L3 are quite nice limiters. Anyway definitely check
the PSP VintageWarmer and Sonalksis SV-315 too.
Personally I don't really like WAVES' modulator effects (choruses, flangers etc.), they sound somehow too cold for me (allthou they work really well in more modern/produced/digital music).
The delay plugin is really versatile in the bundle, but sometimes I find that one a bit too cold also. I like PSP 42/84 Lexicon models, great delays.
For the verbs I would definitely go outboard.. RVerb is "okay", but outboard is so much better. Try Lexicon or TC they will beat the RVerb, no doubt. WAVES has that IR1 impulse response verb thou. It sounds quite good but takes _alot_ processing power and isn't included in the bundle. For a good free verb try the SIR and download some free Lex/TC impulses, way better than any verb in that bundle.
That bundle also includes quite nice tools for some mastering (if you don't have the money or time to get it properly mastered).
Overall I would try to get some outboard FX boxes to complement the bundle (the unit should have digital in/out). I would do this especially for the verbs, so my choice would be propably somewhere like Lexi/TC. Hope this helps!
