How does the Pegasus Plus 2 differ from the Pegasus Plus?

Nike says the Plus 2 returns more energy, has a roomier forefoot and a more curved toe, and uses a lighter mesh upper. The core setup, ZoomX foam with a forefoot Air Zoom unit, carries over.

Is it good for everyday training?

Yes. It is built as a cushioned daily trainer for neutral runners, with enough foam for easy and long road runs. Its soft ride and exposed outsole make it less suited to heavy mileage on rough surfaces.

Does it fit true to size?

Nike describes an accommodating fit with a modified forefoot shape that gives more room around the toes. Runners between sizes or with wide feet may find the standard size comfortable.

Can I use it for speed work or racing?

It can handle tempo runs, but it is a training shoe, not a racer. Runners wanting a firmer, more precise feel for intervals usually pick a lighter tempo shoe.

Nike lists it at about 265 g (9.3 oz) for a men's US size 10, which is light for a cushioned daily trainer.

Is it a stability shoe?

No. It is a neutral trainer. The soft ZoomX foam and curved toe give a less grounded feel, so runners who need pronation support should look at a stability model.
