Xilinx has the best silicon. Everyone else is behind. Altera is basically dead thanks Intel. Lattice is nice for low power but performance-wise they are behind. Don't know much about Microchip, but from the little I've heard their tooling is a disaster even by the standards of FPGA tooling. Then there are Gowin (not bad, but Chinglish docs and everything), Gatemate (pretty innovative and vendor-backed nextpnr support - but only one low-mid FPGA with a promise to release chiplet assemblies of it latter). And Effinix - don't know much about them, do anyone have experience?
