The standard domestic "face frame is better" arguement. Edgeband a pain ? Mmmm, Ok. You don't like doing it - fair enough.
-but-
Milling frame material to thckness and width + cutting it
accurately to frame size with openings + drilling pocket holes + gluing + squaring and clamping the frames up. All that ain't exactly easy. Or fast. And you still have to attach those frames to your carcass. That operation takes waaaaaay longer than ironing on edgebanding and trimming it. If I have an automated edgebander and you have a kreg jig, I've completed two set of cabinets and am in the pub before you've finished attaching your frames to one set of cabinets. If you have an automated pocket hole machine................we can still disagree on what's considered a pain since I'd rather go to the dentist than make pocket holes. And you still won't be faster.
Sure euro hinges are availble for frames, but the winged mounting plates just aren't as sturdy on a frame as they are on a carcass side. And the mounting screws often split the frame because no one pre drills them.
Integrated scribing material ? Big whoop. This sounds great, but installers hate you for it. They have to manipluate an entire cabinet in order to scribe to a wall rather than a separate filler. This is esecially fun with a 42" tall wall cabinet that is 36" wide. Double the fun with a 8-9ft. tall cabinet. Additionally, that scribe is never in plane with the doors on full overlay - a faux pas on a good day and unacceptable on higher end jobs. Plus, you've got to be sure to have an extended stile on those wall sides which complicates your frame layout and cutting in the operation above. Frameless affords a two piece filler that is easy to transport , handle, mark and scribe; and it looks better flush with the cabinet faces.
Edges just don't take that much abuse on a euro cabinet. Perhaps a "frame" is more durable but edgebanding is plenty durable enough. One can even use 3mm solid wood edgebanding if they are especially concerned. And most framed cabinets have lippage on the interiors that invite wear/abuse because the things you'd slide off the bottom shelf hit the lip. No such problem with frameless, which kinda makes the "durability" issue a bit of a red herring.
And I'm certain you don't want to talk about what a pain mounting drawer runners is on framed cabinetry. Split frames, side packers, rear brackets - makes me want to go to the dentist again.
But hey, love me some full inset framed cabinets. Especially beaded, there is just no way that can be replicated with Euro construction. We're not talking about that here though.
