My favorite blades are large Sheffields, or larger blades period, and framebacks, the French ones, Swedish, and I have a Wosty and W&B frameback.
They are lighter, many have blades that can be swapped out as in two, three and seven day sets, and basically I find them no different to shave with except for one caveat - they tend to be so much lighter, that you need to use a more firm stroke with them.
Once you have a shave with a frameback a few times, you'll come to see how unique they are, and I seem to consistently get great shaves from them. Here's a couple of my favorites, with the Thiers #69 being the first frameback I used and which surprised me at the perfect shave it consistenty delivers.
TI #69 - I have two of the #69, and a TI #19

Personally, the edge feels somewhat different when I use them, but once you realize that framebacks are just "different", and adjust your hand (again, I find they need a firmer hand), you may find, as I do, that they are superb razors.
A myth about framebacks is that they were a cheaper version of a "real" straight, while this might be true in some cases, the vast majority I've seen are of superb and intricate construction. Give it time, make sure it's got a great edge, and I'm positive you'll come to really enjoy these blades - aside from the big Sheffields, these are the other type of razor I'm a collector of.
