I am 6`4 so give you some idea of comparison. I have a 1972 CB750 and a 1974 CB750. I have tried many different types of bars and will depend on what bars work for your arm length and what seat you are using.
1. Euro bars/stock seat - very comfy up to 75mph. Slight lean forward. Good on naked bike.
2. Superbike bars/stock seat - not so great on the highway as too much wind resistance, shoulders are rounded.
3. CB75K1 bars/stock seat - the best yet with the stock seat. Good up to 80 mph and ok after this but wind resistance becomes a factor
4. Tommaselli bars/Guilari seat - excellent combo, very comfortable on long haul and good up to 100+ mph with no wind resistance. Very hard to find these bars. With stock seat they feel completely different.
Here are a few pics:
