What are the best bed liners for a GMC Sierra 1500?

Just picked up my 2024 Sierra 1500 Elevation in that titanium rush metallic color and man im stoked its my first brand new truck ever like seriously first one with under 10 miles on the dash and I wanna keep the bed looking fresh but actually functional cause I plan on using it for more than just grocery runs. Its got that short bed and I'm already planning a bunch of trips this summer.

Ive been doing some digging online and everyone keeps talking about Line-X being the gold standard for spray-ons but honestly the idea of someone sanding down the factory paint on a truck I just signed my life away for makes me a little nervous plus I heard it can fade or get chalky after a few years in the sun and I live out in Arizona where the heat is just brutal. Then I saw the BedRug stuff which looks really cool and easy on the knees since we do a lot of camping and I might sleep in the back sometimes but I worry about it getting soggy or smelling like mildew if I throw wet gear in there after a weekend at the lake. Some guys on another forum were saying the velcro on those doesn't hold up in the heat either so thats another thing.

My budget is around 700 bucks maybe a little more if it's really worth it and I really need to get this sorted by next Friday because we have a trip planned up to the Mogollon Rim and I dont want my gear sliding all over the bare metal and scratching it up the first week I own it. I looked at the drop-in plastic liners too like the ones from WeatherTech but people say they trap water and rust out the bed over time so now I'm just second guessing everything lol.

Does anyone have a favorite setup for their Sierra that actually stays looking good but can handle some abuse? Should I just bite the bullet on the spray-on or is there a better middle ground I'm missing...
