The zoom was great. Shift-queuing was good as well. The mechanics and UI of the game is probably still one of the best of any RTS.

I just didn't like the actual gameplay that much. It didn't feel like TA at all. The factions, the units, the maps, etc. It wasn't as fun to play. To me the whole feel was much too serious and a lot of the units I really liked weren't in SC.

That combined with the performance issues early resulted in me not playing it as much. I just continued to play TA: Spring. And if I remember correctly they dumbed down the resource model in the sequel.

And god, I have horrible memories of GPGNet. There were so many technical issues with the game when it came out.
