Are all "Slide Outs" created equally? What to look for

We would not go back to an RV without a slider. Our single 6' electric slider is perfect for the 2 of us. In our previous rig, maneuvering in and around the kitchen/dining/living areas was difficult for 2 or more people. Not any more. Ours does not leak nor caused us any problems over the years.
