Mavericks 10.9 Mail.app solution for Gmail Accounts

It’s not you mail.app, it’s me. I swear. You’re great, you’ve been great, you always will be… great. But I’ve grown I need a mail client that can sort mail and sync the changes accurately, I need a client that doesn’t try to give my email a face lift. I didn’t needed you to be pretty, I didn’t need you to impress my friends, I just wanted you to work with me, for me, usefully. But now we’ve alas grown apart, drifting silently away from each other like two rafts in different currents on the ocean. Perhaps we’ll meet again, perhaps not, regardless I just want you to know that I’m happy and I’ve found a client that works for me.

Mail.app has been dumped on my computer, it has simply too unreliable to work with my daily bread and butter email, I find it slow, clunky, and unreliable. It fails on any sort of message management on a Gmail account, as well as quickly finding contacts from my address book. I’ve moved on to Mozilla Thunderbird, it’s way way faster, easily rivals Apple’s Mail.app program and is leaps and bounds ahead of the pack for functionality. All the clients listed here were tried, and all either didn’t hit the mark or failed.
