I'm a huge fan of the Beacon v1 -- absolutely my favorite shoe of all time. I've gone through 4 pairs and still have 3 new pairs sitting on a shelf. Many people seem to wear these for easy/long runs, but because of their light weight I use them for workouts and races (HM and marathon) with great success. The perfect combination of light weight, cushion, and responsiveness. They may not be super durable, but I'm in Clydesdale territory so I'm luckly to get 300 miles out of any shoe.
The Beacon v2 is "OK" in my opinion. The fit is slightly different than the Beacon v1 (more room in the toebox), and I'm in size 15 so I can't just go down a half-size. It's equally as light as the v1, but there's just something different about the fit and feel of the v2 that I don't prefer compared to the v1. The fit feels a little sloppy. The large heel tab on the Beacon v2 did not bother me at all.
The 1080 v10 is a good-to-great shoe for me. This is what I use for easy and long runs due to the cushion. It's definitely significantly heavier than the Beacon, but it feels significantly more plush. Because there's no exposed foam on the outsole it should be more durable than the Beacon, but the added rubber makes it heavier. I've never really used it for workouts before, but I think it would be fine for tempo-ish pace, but just a little heavy. For me the fit of the 1080v10 is spot-on. Right out of the box it felt comfortable. Other than the weight, the only other major downside is the price, about $150 from what I remember. It also has a bit of a heel tab, but I don't notice it at all.
