Key differences
The 5CEA7 has about 34% more logic capacity (113K vs 84K LUT4 equivalents).
They use different logic architectures: the 5CEA7 is built from ALMs and the LFE5U-85 from LUT4, so the raw LUT counts (56.5K vs 84K) are not directly comparable.
The 5CEA7 has more on-chip memory (6.7 Mb vs 3.7 Mb).
The 5CEA7 is designed with Altera Quartus Prime and the LFE5U-85 with Lattice Diamond.
