Summary
The Mazak VARIAXIS i-300 and the Mazak VARIAXIS i-300 AWC are the same compact 5-axis platform listed in two forms, and most figures match: 350 mm (13.78 in) X, 550 mm (21.65 in) Y and 510 mm (20.08 in) Z travel, a 65 kg (143 lb) table load, a 12,000 RPM spindle, 145 tools, 60 m/min (2,362 ipm) rapids and MAZATROL SmoothAi.
The differences are in the spindle listing and options.

Verdict
Treat these as one machine. The continuous spindle rating, travels, 145-tool magazine and 65 kg table load are the same, so the choice comes down to configuration. Pick the listing with the BIG-PLUS BT40 or HSK spindle, higher-speed spindle options and tool expansion to 505 for long unattended runs of varied small parts; pick the CAT No.40 build when the shop's tooling is already CAT 40.
