As an old lag who did the IMCR, and an (FAA) IR, I would say "What are your ambitions?" What would stimulate you?
Drilling holes in clouds can get very boring very quickly. As someone said, the inside of one cloud looks very like the inside of another. But - with the IR you can fly through the clag over "home airfield", and off into the bright sunlight of somewhere else. I've done that many times. If it's hissing down with rain at home and at proposed destination, I usually don't bother to go.
If seeing the world is your thing, sightseeing from aircraft, and visiting places, can be brilliant. For me, flying over the Grand Canyon, and around Arizona and California, landing at Sedona and the like, is fantastic. I remember landing at Palm Springs, wife and me deciding it was too hot (35 degrees C), so we took off again, and landed at Big Bear City, 8000-ish feet up in the mountains, where it was around 20 C.
I've had as much fun in a taildragger landing in fields on Exmoor. It's a different sort of fun. I'd do both, but certainly don't see a high-tech glass cockpit as the ultimate flying machine. I fly an old Arrow, and that is ideal for 90% of the time.
