In terms of handle comfort, some knives are notoriously good. The three "Ms" by way of example: MAC, Masamoto, and Misono. If you like Wusthof classic at all, you're going to love those. Some knives have known peculiarities. For instance, Hiromoto handles are narrow. Togiharu handles a bit short. Glestain is awkward for big hands. Etc. The more specific you are about which knives are under consideration, the more specific we can be about issues.
People who talk about "balance," generally don't know much about knives or how to use them. Unless the knives are specifically balanced, like Gude Viking or Global, the balance point changes with the length of the knife.
Rat tail knives are more balance forward than full tang knives. Longer knives are more balance forward than shorter knives. German profile knives, because of their bolster design, are slightly more balance neutral (balanced at or just in front of the finger guard) than French knives. Knives with finger guards (most European and American which actually have bolsters) tend to be more neutral than knives without bolsters or without finger guards.
Japanese manufactured knives are almost always considerably lighter than their western manufactured counterparts, this tends to make them feel less balanced. In the store, the balance seems important. However, over even a short time (a couple of meals at most) weight matters a lot more; and the imbalance, such as it is, begins to feel natural.
I suggest contacting MAC through MAC USA. They have a pretty good distribution system and you may be able to find one you can wave around and pretend to cut with -- if that's important to you. (MAC also has excellent customer service and a great guarantee. The MAC Pro should be on your short list.)
Some others: Masamoto VG; Togiharu G-1 (slightly more affordable clone of the Masamoto, F&F and handle suffer a bit by comparison); Misono Moly (great handle, okay steel); Misono UX-10 (great looks, great ergonomics, maybe too expensive); Hiromoto G3 (great stainless); Hiromoto AS (excellent carbon core, surrounded by stainless); and the Hattori forum knife (same review as the Misono UX-10).
I'll need a signed waiver before I get into a discussion of carbons. Basically you want to look at Misono Sweden, Kikuichi Elite, Thiers Issard **** Elephant Sabatier, K-Sabatier, Masamoto CT, Masamoto HC (would probably be my first choice if I were starting over, but expensive), "Nogent" Sabatier, "Massif" Sabatier, and "Canadian" Sabatier. For the record, I own a bunch of Sabatiers -- most of them pretty old.
Shun are not bad knives, and neither are Masahiro. But they aren't in the same league as the other Japanese knives manufactured. That said, they're much better than Wusthof or almost any other western knife -- at least in blade quality. I'm going to paste a link to something I just wrote in another thread that goes into some detail about Shun, Wusthof Classic and their ilk:

If, after all that, you're still at all interested in Wusthof, you might want to take a look at the "Le Cordon Bleu" Wusties at Cutlery and More. The LCBs preceded the Ikon lines, use the same steel (X50CrMoV15), the same cut down bolsters no finger guard on the choil, and are ground to the same 15* bevel (Classics are ground to 20*). They seem to have been discontinued, although they're still on Wusthof's website they aren't available from very many retailers. Cutlery and More has a few shapes and lengths, and have them at a very good price. They may be the best deal going in German knives.
Hope this helps,
