The new standard PT plugs are great. EQIII, De-Esser III (?), are fantastic for most things. The compressor is actually quite good as well -- still prefer my McDSP plugs, but it's great for a processor-friendly compressor when you've maxed out a lot of your CPU -- or just for a change in color from your other stuff.
The D-Verb is indeed, as noted, utter crap. It's harsh, the resolution is horrible, it just stinks. You can do really well by looking at other companies like McDSP's Revolver or the Waves R-Verb...both companies have "LE" bundles that are pretty affordable and give you a major performance boost regarding the quality of your mixes.
McDSP has the "Project Studio" bundle and Waves has "Musician's Bundle" and "Musician's II Bundle". Both companies offer educational discounts -- so if you're a college student, you may want to ask them about it.
Logic does have some great standard plugins from a sonic standpoint. However, I find the Pro Tools plugs to be much more user-friendly and easy to use -- thats partially due to the great GUI the developers put into them.
All in all, I find, having used both, that Pro Tools is much more efficient for singer/songwriter types. It's easy to import MIDI data and assign to Reason or whatever Softsynth you may have. It's also easier, from a visual and signal routing standpoint, when recording yourself -- vocals, acoustic guitar, piano/keyboard, etc.
