I second the vote for (real) pallet forks. Real forks help keep the CG of the load closer to the tractor which improves max weight handling, safety, and strain on FEL.
I can switch between bucket and forks in a couple minutes and it isn't difficult. Adjusting the distance between the forks is way easier with real forks. Lots of home brew and many factory made bolt/chain-on don't adjust or don't adjust nearly as easily. You don't have need of having to wrestle with heavy forks if you are using a quick attach system.
When you turn the steering wheel all the way to one side it changes the suspension geometry and makes you subject to a roll over if you have a heavy load on the forks. This effect is exaggerated if the load is farther out in front of the tractor as it is with bolt/chain-on forks.
I'm not saying bolt/chain-ons don't work. Everything is a trade off, price, safety, max load, convenience and so forth. Even if all other factors were the same (and they aren't) I would personally hate to have to wrestle with the forks. Depending on what I am doing I may switch back and forth a few times in a day. That alone would be a BIG DEAL with bolt-ons but it isn't with quick attach.
If you are always going to handle light loads, have plenty of maneuvering room, flat terrain, and never take the forks off then ask yourself why you bought a bucket.
