What actually matters more is the Database you're using. Soon or later (better soon) you'll have to either built or buy one and maintain it for yourself and your own needs if you want good results.
Take a look at AdvancedSubmitter.com and
http://updates.advancedsubmitter.com/, uses these DBs as a starting point, add your own Partner Accounts, and remove those sites that never list you. Within 1-2 month you'll end up with an almost complete submission list.
For Partner Accounts (you'll need them ASAP) take a look at
PartnerRequester.com, there you'll find 1200 TGPs and MGPs to apply
