Actually FRS/GMRS is far superior to CB but when you consider your type of communication you need to consider your riding group. CB's are quite common with most touring riders because A, many top line bikes come with them or have them as integrated options and B, many long distance riders want to be able to communicate with truckers and others and a CB is still the universal means of that type of communication.
I ended up putting the $600+ CB into my Goldwing because the rest of my family already had CB's on their bikes. We just did a family run of about 1500 miles up through the N. GA mountains and being able to communicate without hand signals was wonderful. In fact, I had a new Garmin nuvi so I was relegated to navigator but my Father-in-law really likes to take lead (he's concerned that others may not pace the ride to suit my Mother-in-laws comfort level) so he lead and I gave navigation instructions from the rear. It actually worked out real well and would have been impossible without the radios.
Another point in favor of CB's is when riding in a large group. If you have folks at each end of the group keeping track of where everyone is, especially when stuck in traffic or going through traffic lights, it really helps to keep the group together or allow them to regather after being separated.
