WRT clock speed, the fan-out of your net is going to drive your Fmax which is highly dependent on the application of the FPGA. Much like CPUs you can't just compare Mhz X to Mhz Y, even moreso considering how parallel FPGAs can get. There's also been some neat low-power parts lately(from lattice and others).
