I had an older MUSA AHH 61 (2006-ish?) and a Taiwan Sam 62 (2015-ish) with 2TT and for a brief spell I also had a 2TT 58. All of them were 700C. I should also say that they are all gone at this point, nothing wrong with them except my own unnecessary searching for the next shiny object.
Both are amazing frames and can be set up very similarly - I think your tires, racks and handlebars would probably determine the feel and ride more than the frame geo, tubing or anything else.
Some details on the way mine were set up: both had front and rear racks, sidepull brakes and short stems:
AHH 700x38 + dropbars
SH 62 700x44 + dropbars
SH 58 700x42 + Albatross
It has been said that the Sam is burlier or that the tubing on the Homer is slightly lighter and the lugs are more elegant. To me, they were both equally capable, perhaps the 2TT Sam felt a tad stiffer particularly when loaded, but it certainly didn't feel slower. Also, at no point did I feel like my AHH couldn't carry as much as the Sam.
Are you trying to decide which one you'd buy? If so, I would choose based on availability, color, badge, name, which one do you find more beautiful? Oh and sizing: which one fits you better? If you can find a frame where you fall in the middle of the suggested PBH range for either the Sam or the AHH I would choose that.
Not sure if this helps, but I think Grant said it best when he said it was hard to tell one from the other when you were riding them.
Best.
