Leadjoy really surprised me! I've ordered the PS style layout controller from them too (Saber Plus) as I do prefer the PS stick layout - but that won't arrive for a week or two and I've been really happy with the Xeno Plus. The Saber Plus also goes from 4 back buttons to just 2 - but has the extra 2 shoulder buttons which I think is my preferred approach for additional buttons (4 in total, 2 rear, 2 shoulder).
Saber Plus arrived on Friday so had a chance to use it Friday night and Saturday for a bit.
I think it does a lot of things really well (especially for the price) - but I'm not a fan of the triggers or how the top of the controller is shaped. When I hold a regular Dualsense my entire finger can be around the top of the controller and hover over the bumpers/triggers, means I can quickly press either but also means I can spam R2 really quickly.
The Saber Plus is quite narrow at the top so the tip of my finger almost extends past the triggers onto the extra shoulder buttons. It means I can't really spam the triggers like I normally would and I have to angle my finger a little more to press the bumpers/triggers. I also noticed I was firing single fire weapons a lot slower than usual.
If you've got smaller hands I reckon it's a really good choice. ABXY buttons are nice, sticks are the, now usual, JS13 Pro TMR sticks so feel really responsive and perfectly linear. Back buttons are fantastic, similar to the Xeno Plus with the feel and placement.
Honestly I think Leadjoy have got 2 fantastic options available right now. The Xeno Plus is probably the one I like the most (despite my usual preference of a PS stick layout) but I'm sure if I stuck with the Saber Plus I'd get used to it in no time. I mainly prefer the Xeno Plus because it allows me to hold a controller how I normally would.
The pricing is also great, Xeno Plus for 60 quid on Amazon and Saber Plus for $60 right now from Gadget Hyper (with around a week time for delivery).
