I've become a huge fan of Eggbeaters. In the process of converting all of my bikes. I suffer no hotspots or any other issues. But that could just be me or my shoes. I don't know. I've been riding clipless for close to 20 years and never have experienced hotspots so I might not be a good judge of that. But they clip in and clip out very easily in all conditions, give a good amount of float and are extremely simple and minimalist in their design and construction.
