As others have mentioned, it's subjective and personal preference. What I like best may not suit you well.
I've been behind a lot of stocks and chassis', and I really like the JAE. It's super comfortable - you will hear this a lot from JAE advocates. Commonly stated as the most comfortable stock/chassis option on the market. Quality is great, design is superb, CS is beyond excellent, and great features and accessories available. It's definitely not cheap, but you get what you pay for.
I started with stocks, but have since switched over to chassis. I hate how stocks "come as is" and require any gunsmithing work if you want to make changes (or work by someone comfortable with drilling and working on a ~$1000+ fiberglass stock - could be you). Doesn't have sling studs where you want them? Need to work on it. Need a picatinney of ARCA/RRS rail? Stock will need work. Want to try a different action, or ever upgrade the action? Need to remove the old bedding and have a gunsmith bed it. What about wanting a thicker barrel contour? Hopefully the barrel channel is large enough. Etc, etc, etc.
I've found chassis to be a lot more versatile and "future proof" over their stock counterparts. Of course, not all chassis' are equal. I really like that I can swap out barreled actions when I get the itch, add rails as need be, bag riders, NV bridges, etc. You simply can't do that to a stock without a lot of work.
Of course, you may prefer a stock and know exactly how you want it, and have no plans on changing actions in the foreseeable future.
