According to shimano's site both these CRANKSETS are hollowtech 2.
The 34 tooth chainwheels on both, are identical (same part number.) The 50 tooth chainwheels are NOT interchangeable.
The fc 4550 is a Tiagra level component
The fc r600 is an Ultegra level component
Usually a more serious rider would select the better Quality ultega components. Both ware and performance is better.
If your not doing a heap of distance the Tiagra components will serve well enough and are cheaper.
If your contemplating fitting the fc r600 chainwheel (50 t) to the tiagra level components don"t bother it won't fit.

Although Shimano has really advanced in the use of cutting edge technology for parts, your question of weight in that particular part of a bike is a little weird.
Keep in mind that the crank is probably the most abused part of a bike and shaving a few grams just has a potential to make it weaker- where you can least afford it. On top of that, by saving the same weight- lets say 30 grams- on the tires it will provide you with an equivalent 300 grams in performance improvement and not risk loss of strength just for the sake of weight.

They are hollowtech II cranksets but I have been unable to find a site with their respective weights.
