depends on what you mean by "better" really, it would definitely be much better if i could port forward (so everyone could be able to download), but it would also be much better if i didnt turn off the computer at night lol
i also have a lot of near-0 torrents, often just from private trackers where there's much less action (on AB my raw ratio is 0.01 lol), i think having port fwding would help with that a lo
anyway, during seeding my connection speed is rarely the bottleneck, as my seeding upload rarely reaches 1MB/s (and sometimes gets to like 40MB/s, which is neat even if rare)
