I'd have to go with Wolfgang on the Healey or the Triumph TR4. Both are chromed and VERY elegant and designed for the period. More over, they were designed and manufactured for what was a higher priced car than the MGB.
The MGB items are, perhaps, just as nice, but would take a little work in painting and all, and were made for a lower priced car so they don't have quite as much class built into them. PERFECT period touch for a racing/outlaw Speedster, but I'd definately go with the beautiful chromed ones for a car done up the high level that I've seen here. I have a pair of original 356 Pre-A handles and TR4 handles and I really think that the Triumph items are a better design and a more appropriate size for the door space provided.
My opinion.
