As per the Singletrack tradition of “recommend what you have” I would seriously recommend the RocketMax. Just got it around a month ago and it’s such an amazing bike. Descends better, jumps better, climbs better than the bike it’s replacing, I’m able to keep up with mates I never thought I would be able to now, so it’s objectively quicker if that’s what you’re in to.
Won’t fit the 230×65 I assume you have (out by 2.5mm on the stroke volume), but I’m really impressed by the DB Kitsuma, you’d get a fair chunk for the shock selling it on I’m sure?
They have stock of L and XL in both colours right now so you would def have it by July. I’ve bought a rocketmax full bike and Bfe frame off them recently and they’ve been such lovely people to deal with that in the unlikely event something did go wrong they’d sort you out quickly no bother.
Also you mentioned the weight of the privateer as a con – rocketmax was the lightest of the test bikes in bikeradars bike of the year test as well
