I mostly like the basically foolproof install and tall height limit and easy adjustments and marketing getting the RF to two message out. I was mainly a babywearer and used convertibles RF, but ended up loving my infant seat for my third child, because it allowed her to fit much more easily into my already-full life with older kids (one time we went out to eat when she was 15 months and napping in the bucket? Priceless experience, lol). Also good for people who travel by plane/taxi/friend's cars, bucket is almost always easier than any convertible.
So for mom q public who can't wait to FF at 1 but just got the RF to 2 message, it's a good deal (I see way, way too many kids crammed into buckets because parents are waiting for them to hit the weight limit, without regards to height limit. Sigh. It was the same way with the tiny pegs and snugrides back when kids were crammed in THOSE till they hit one. Double sigh). And for parents who can't install seats with the right recline, or who want a solid lockoff for a center belt install (Graco doesn't have any other base with a lockoff at BRU), it's great.
Anyway, I could go on, lol. I run into such a plethora of misuses of infant seats, that one that's relatively straightforward for people to get right just makes me happy (even the Key Fit...uh, duh people, there are different harness slots for a reason...why can't that thing have a no-rethread headrest, anyway???)
For most of us, it may well be too much money for too much infant seat, yeah.
