Flower color will be the same on any oakleaf - white, but will often fade/age to a dusty pink or red, infrequently even a deep wine red.

Maximum leaf size generally develops as the plants mature, but 'Snow Queen' probably produces the largest. Among others, I grow 'Little Honey', a gold leaved variety that is supposed to be compact/dwarf in habit but it is producing some whopping sized leaves this season. Easily 8-9" long and 5-6" wide. And it's about 12 years old.

i dont know what mine is.. but its in full shade ... and such.. can cause a plant to grow larger leaves ... go figure on that ...

I have 'Snow Queen' and the largest leaves are about 11". Quite a large shrub overall, and a beauty to boot!

I have had 'Snow Queen' for years. Huge leaves that can turn mahogany and wine in the Fall. Also have 'Snowflake' and like double flowers, but it is new, and I can't recall any fabulous Fall color.
