"Best" anything in boating is always a compromise
The dinghy choice has always been a difficult one to answer because, as Ed says, what you plan to do with it, and how you use your boat (which we don't know and you didn't say) are critical to the choice.
Hard or inflatable? Hard dinghies rock when you get in and out, inflatables are far stiffer. Inflatables can get holes in them, but they are far faster. When we use our air floor high speed 10'-2" Zodiac Fast Roller with our 9.9 HP engine, we can get up on a plane with four people in the boat. It's great for those longer trips and to scoot across Racoon Strait from Ayala Cove to Sam's for brunch! But most of the time we either are rowing or going slower. A friend in Chicago has a solid Walker Bay 8, rows to his mooring, can beach the boat without worrying about scraping the bottom, keeps it locked on a rack during the week and loves it.
You can always put a smaller engine on any boat, but you can NEVER put a bigger engine on a smaller boat. Usually most recommendations are to buy the biggest one you can. Downside is foredeck space, or, in your case, space awthwartships to mount on the davits. Not all of us have your boat, so we don't know the dimensions.

Also, where you are planning to go with the mothership are also critical: local waters or far afield will make a difference.
Your boat(s), your choice(s).
