I like WG but I have not tried every sealant. I apply with a PC and remove with a MF about 30 minutes later. I have a hard time believing that anything could be much easier to wipe off, but others will differ. Not an issue for me.
I chose WG for look not for ease of use, even though it is very easy to use. I wanted a sealant that looked like a carnauba wax with more of a shimmering liquid look vs. a candy apple sealant approach that looks more like a mirror. People differ on what they prefer and you need to consider look and application ease to meet your values.
You will also find that paint prep before LSP will greatly affect the final look. If you read the threads, some LSPs make a paint look darker and other brighter. Some make metallic fleck pop and others are more muted.
The easiest LSP to apply and remove with the best look that I've used is Optimum Car Wax. You spray it on and wipe it off like a QD. I think that DG AquaWAX is a synthetic wax so more of a sealant than a wax to me, but I prefer OCW.
The WOWA sealants like OS and Ultima might be even easier, but I can only try so many products at a time. Happy to try one but my finances require me to use what I have today (I have some great stuff so I can't complain). CEE DOG and OldTiger will recommend the Ultima WOWA, and I suggest listening to their recommendations. You want easy, well...
If I may be so bold to ask but what is more important to you, ease of removal or best look? I'd rather suffer a little more work (with long term durability) for my preference in look. I might love Souveran Paste but I don't have the time to wax every week. Your situation may be different.
I hope this helps.
