Standard height bowls are about 14" from floor ( plus seat). Comfort height, also called "handicap" toilet, are usually 16 to 17 plus seat.
It is definitely a matter of preference. I am 5'10". I am also 60 and all my joints creak and groan! I prefer the tall toilet, because it is easier for me so stand up afterwards. At home, I have not changed the toilet yet, but have installed grab bars for assistance.
At your height, the standard bowl may be just fine. And a lady who is a coupe of inches shorter than you may find the tall bowl uncomfortable to sit on. If you visit a large public restroom ( theater, airport, etc.) you shoud be able to "test" the different types and decide.
