It's hard to say what the best Mod is for that since I don't hear much from people making TDM games. Some claim they get connection bugs, other people claim they don't get any bugs at all, while others just flat out don't use MP at all.
To my knowledge, only Lemur V2 had TDM as a feature. That feature was dispersed to several other Mods after it fell off the face of the earth. Project Blue has Lemur's TDM, as did S4Mod, but I can't come up with any other Mods than that, so unless they've made their own TDM (Or got hold of Lemur's and didn't ask me for permission to use it) those may be your only options.
Sorry it wasn't the best answer in the world, but I hope that helps.
The one and only,
Only those who sow the seeds of their desires will reap their benefits later.
However, I have seeds of my own to tend to. I don't have time to be someone else's watering can.
