^^ Yes, the syringe applicators are GREAT if the lube is thin enough. I use Silca Synergetic on my road bike and the syringe tip allows me to get a tiny dab right where I need it. This means that less of it gets where you DON'T want it, which makes it much easier to dry the exterior of the chain off before you ride. So, less product is used, and chain stays cleaner for longer. Win/win.
I currently use Synergetic on my road bike (and gravel bike during wet season), CeramicSpeed UFO Drip for MTBs, and Silca Synerg-e for the ebike. I'm a fan of Synergetic for my road bike because it tests well in a lab, is easy to maintain, and keeps my drivetrain dead silent. UFO drip has worked well enough for dry MTB riding (but this is probably best for a different discussion). So far I've had good luck with Synerg-e. Back when I got my ebike I used DumondeTech (yellow bottle) during wet rides, but it would always attract so much crap on the drivetrain. Then I'd clean the drivetrain off between rides and need to reapply. It just seemed to wash out super easy during water crossings. More recently, I switched to Synerg-e and noticed that it does have a bit more staying power. I lube once every 50 miles...maybe? I should keep track. But it does seem to run cleaner than the DumondeTech stuff on the same trails and that's a big win IMO.
Having said all that, I'm not going to sit here and tell everyone they should spend this much money on lube, especially not on an ebike where you can (theoretically) blow up the chain with one lazy shift. But, generally, I've had good luck with using a more expensive lubes less often (vs using a cheap lube all the time) because it means the drivetrain stays happier and there's less cleaning for me. I'm lazy and I don't love cleaning.
