I've tried Swift, Hootsuite, Seesmic, and Twidroid. I keep coming back to Twidroid though and even paid for pro. For a long time, that was the only way I could access multiple accounts. I admit that Swift is, well, Swift, but Twidroid has a richer feature experience that I need to manage my personal account as well as accounts for the companies I represent. Hootsuite is fine, but I haven't gotten used to the UI yet.
