Ilfochrome is not so complicated nor difficult, in fact it's a lot of fun, but being 15 times more expensive than RA-4, there's definitely one requirement over anything; money.
But, RA-4 is even more easy than Ilfochrome, process being more quick and you can do it in trays without any drums, just like BW. And it's cheap to play around.
RA-4 today gives quite vibrant colors, some people even think they are too vivid. So if you find Ilfochrome too expensive, RA-4 print your negs. You'll get excellent results. And if you like to experiment and have slides to print, you can reverse process to print slides on RA-4 paper and the price will remain low. Quality will be so-so with high contrast but colors will be vivid. Look at a thread started by me for a few months ago for examples.
