Key differences
Both devices offer similar logic capacity: 22K and 23.4K LUT4 equivalents.
They use different logic architectures: the EP4CE22 is built from LUT4 and the XC7S25 from LUT6, so the raw LUT counts (22K vs 14.6K) are not directly comparable.
For arithmetic, the XC7S25 has 80 DSP slices against 66 18×18 multipliers on the EP4CE22.
The XC7S25 has more on-chip memory (1.6 Mb vs 0.6 Mb).
The EP4CE22 is designed with Altera Quartus Prime and the XC7S25 with AMD Vivado.
