HBB rec for use in various cars

We are looking for a HBB for our DS1 who just turned 6. He is 48", 47#, and is currently right at the top slots of our TFP. This booster will mostly be for our car-pool arrangement to/from school which is 25 minutes on busy high-ways. Right now, that is in the 3rd row of a Toyota Sienna. Over the years, this seat could potentially be used in a variety of cars and passed down eventually to little brother who is of the shorter stouter variety. It will not be moved around though as he has a dedicated seating position in the car-poolers van.

LATCH and some sort of anti-submarining feature are interesting. Our car-pooler rides in a Britax Parkway in our car but DH doesn't feel like it is very sturdy and didn't like the feel of the Graco Turbobooster either.

I'm sure I'm over-thinking this. I was about to click buy on a Diono Monterey but then saw that it seems to be a bit finicky.

Suggestions? Thanks!

Is there a thread somewhere with a booster selection chart or that lists the pros and cons of each seat for different body builds, car configurations, etc?

In reading through tons of threads, I came up with the following list of seats to look at and would love a more fleshed out synopsis/table including weight/height ranges, whether they separate, etc. than what I quickly threw together below. Ideally would have price ranges included. If there is such a thread or resource somewhere, I'd a link!

- Recaro Vivo - doesn't need vehicle headrests, surounds child well, good for narrow kids (not sure about not so narrow kids???), no LATCH

- Recaro ProBooster - nice SIP, no LATCH, big headwings (kids lean forward to look around and move out of position?), tippy?

- SunshineKids/Diono Monterey - LATCH, anti-submarine feature, older/new versions fit different body builds differently, issues with shoulder belt guide in certain types of cars

- Britax Parkway - option for latch - doesn't fit narrow kids well, anti-submarine feature

- Cybex X-Fix - LATCH, reclining headrest, fits narrow kids well (not sure about not so narrow kids???)

- Graco Turbo Booster

- Evenflo Amp Highback

- Clek Oobr (out of our budget)
