A bunch of good options discussed here, and I have experience with most of them. I think the Misono 440 is a pretty good choice for what you are looking for, and Misono designed this series pretty much targeted for your market, easy-to-sharpen solid performing line suitable for pro-level use but still relatively affordable. April Bloomfield is a well-known chef that favors the Misono 440 and I've heard of others.
A couple things to be aware of though for Misono gyutos:
1) There is a big jump in blade height, weight and heft, handle size from 210 mm to 240 mm - see this
table for numbers. So while the 210 mm is relatively light (not quite laser) for a Western gyuto, the 240 mm is a bit towards the heavier side compared to peers (though not quite as heavy as say a Masamoto VG). However the 270 mm is only slightly heavier than the 240 mm and the even balance makes Misono one of my favorite makers for a 270 mm Western gyuto.
2) The 210 mm (and probably the 180 mm) gyutos have pretty low blade height, so they can feel a bit like a "tall suji". I have a Misono 440 210 mm and I don't mind this and I appreciate the variety this profile offers among my collection, but it may not be for everyone.
Another one to strongly consider is the aforementioned Masahiro MV 137XX/MV-Honyaki 148XX/MV-H 149XX series. Just well designed all around, comfortable handles, pretty flat profiles (but still allow some amount of rocking), easy-to-sharpen relatively fine grained steel that holds an edge almost as well as VG-10, but is much tougher and resists chipping. The 137XX series knives are heavier and more workhorse-types, whereas the 147XX/148XX series knives are lighter and thinner, pretty close to laser.
Tojiro is undoubtedly a good value, but either the Misono or Masahiro are more comfortable to use IMHO, and the steel is tougher. Also I'm not a fan of the profile of the Tojiro; the whole edge is gently curved and doesn't have a flat spot whereas both Misono and Masahiro have quite generous flat spots. They should have a bit better edge retention than AUS-8 like Fujiwara FKM or Suisin INOX.
