Key differences
The XC7S75 has about 37% more logic capacity (76.8K vs 56K LUT4 equivalents).
They use different logic architectures: the EP4CE55 is built from LUT4 and the XC7S75 from LUT6, so the raw LUT counts (56K vs 48K) are not directly comparable.
For arithmetic, the EP4CE55 has 154 18×18 multipliers against 140 DSP slices on the XC7S75.
The XC7S75 has more on-chip memory (3.2 Mb vs 2.3 Mb).
The EP4CE55 is designed with Altera Quartus Prime and the XC7S75 with AMD Vivado.
