I don't agree with the OP that Gears 2 is worse then gears 1. I personally hated the shotgun centric Gears 1 multiplayer. You would usually just have two groups of 4 run at each other and it would be over in 30 seconds. I find the Gears 2 matches far more strategic without the mindless bunching up in a single doorway area.
Horde is a very good addition, it is of course hard for me to think its too amazing due to playing a lot of R2s vastly superior coop (has classes, multiple maps with dynamic objectives, 8 person teams and great interplay/difficulty). It is a lot better then Gears 1 but on the multiplayer it doesn't come anywhere close to R2 (its not even close in competitive, 5 vs 5 just doesn't cut it any more then 4 v 4 did. Again, of course, comparing it to R2 with the 5 person squads as a part of a 10-30 person team fighting over objectives, WAY better).
On the bright side I did like the Gears 2 single player better then the Resistance 2 single player. The weapons are certainly much better in Resistance, but the connection to the characters was way better in Gears 2. The built in co-op was pretty nice too with two continuous characters (R2 has a few characters that pop in and out, and a kinda awkward Co-op 2 person game that I don't think is playable online).
I played through Gears 2 single player and it was fun, but honestly ever since that and a few shots at horde mode/multiplayer I went right back to leveling up my medic in Resistance 2.
I know some will say I'm just biased, but I'm 100% glad that I rented Gears 2 and bought Resistance 2, it just has so much more to like.
