In 1/72, the Hasegawa kit is well regarded, but it's old(ish) and has simplified cockpit and wheel well detail, plus no detailed engines. The Airfix kit is the newest one on the block, but I have not had a look at it. Revell Germany's kit looks nice in the box, but I was not impressed.
In 1/48, the DML (ex-Trimaster) kit was king of the Me-262s, and did have full engines, but lacked plumbing. I found this kit very accurate and well detailed overall, but it was fiddly to build and had some fit issues particularly the engine/leading edge fairings and the lower wing. The Hobby Boss kits are the newest 1/48 Me-262 kits, but again I don't have any of them so cannot comment on their quality and accuracy. Tamiya makes a nice looking Me-262, which I am sure goes together well. The Monogram kit is very old, the Lindberg kit is a dinosaur.
In 1/32 the Trumpeter kits are probably the best, although Revell Germany's new 2-seat night fighter has a more accurate lower canopy sill for that particular variant. (Trumpeter's night fighter canopy supposedly more closely resembles the trainer version.) The Revell kit has full engines like Trumpeter, but is dirt cheap compared to Trumpeter. I think both have separate leading edge slats, which on the real machines drooped down when at rest (they were air-loaded so closed auomatically during flight). Hasegawa and Revell USA both have very old kits that are best forgotten given what is currently available.
