Recommended Bittorrent Client?

I'm currently running the official (raw) BitTorrent (3.4.1 I think) and actually been running it for awhile now. But I hate it when I'm down/up-loading multiple files simultaneously because of all the open windows. I never tried other clients (except for the experimental one but I moved to a different system and never thought of installing it again). But I now I want to try one of those client that let me run multiple torrent within the same window. Is there a particular one that is highly recommended?

Thanks for your time.

I like shadow's BT

I've used the original, exp, shadows, abc, and torrentstorm (among others that are completely garbage) but honestly I've gone back to the official bt client, with multiple file support you can fine instructions for this here : Kirika's Guide on Multi-Seeding

I have found using ABC easy and effient. So far I would recommend it.

how do i get this shadow's bt?

go to www.bt.degreez.net. They have the shadow client. I use it and its the best, I've had no problems so far.

yeah i agree with NarutoMaster. I stick with shadow as well.
