Hi!
From what I see it very much depends if you fly for a private owner, corporate owner or public transport company (AOC holdrr). There are some large AOC bizjet companies who operate not very differently from airlines so coming from the airline environment this might be the best choice. I fly both for a corporate owner (very relaxed, you know all your passengers, no catering is required, most flying dates are fixed at least two weeks in advance, almost always back home in the evening) and a small AOC holding company. Not big enough for proper crew rostering (the most difficult thing to adapt to: Not knowing when your next flight will be and how long you will be away) but luckily big enough for it's own maintenance and OPS department with dispatchers and everything. Which means we only have to fly the aircraft (and tidy it up away from home) with everything else being taken care of.
Flying for a private owner can be heaven or hell, from what I see it is more often hell than heaven.
