I've ridden clipless ever since the first LOOK pedals became available back in the late '80s. Over the years, I transitioned from the original LOOK system to the Shimano SPD-R system and SPD ("mountain bike" style). I'm one of the few who actually like the SPD-R system, so I've never seen the need to change to anything else.
I think the SPD system is pretty versatile; there are plenty of styles of pedals and shoes available... it's easy to clip in & out of them. So that might be the ticket for you.
For serious and semi serious road riding and training, clipless is the way to go.
