all those mentioned above are comparable to 054A in what they have and do. You can go through each of them and state what the advantage or disadvantage over each other are. And I've had so many arguments with others on 054A vs Formidable. Let's just say 054A and the La Fayette variants with improved air defense are pretty comparable. None, you can really truly say is just that clearly better than others.
The Singaporean Formidable has a more advanced SAM and radar combination; The Thales Herakles radar on the Formidable is a phased array radar, and is a multifunction S-band radar. It has a longer range, has less moving parts and is more modern than the Fregat-MAE-5, which was originally designed during the Cold War. The Herakles radar combines two radars into one; a search and track radar and a fire control radar. On the Type 54A, this is achieved using three radars; the Fregat-MAE-5 as a search and track radar, the MR90 Top Dome system as the SAM fire control radar, and the Mineral-ME as the anti-ship missile fire control radar.
The SAM system on the La Fayette derivatives is also more modern and capable; the MBDA Aster is a terminal actively guided radar homing missile which entered service in 2001. The SA-N-12 was originally deployed in 1979, and is a semi-active radar homing missile. Aster has more range and better manoeuvrability compared to the SA-N-12 and its Chinese equivalent.
With the Australian Anzac's, to make things quicker, the Anzac's will fitted with a IRST, and will also receive a phased radar array as well, on top of the current radar systems. ESSM is also being fitted, which has a longer range and better agility compared to the SA-N-12 and its Chinese equivalent.
That's more an attribute to Canadian training rather than the platform itself.
Part of it is training, part of it is the package; the CANTASS sonar system is perhaps one of the world's most capable sonar system. Although the array itself is the American AN/SQR-19, we've upgraded the back end with a Canadian signal processing system that is more powerful. Also, the Halifax class frigates are capable of launching and recovering helicopters up to sea state 6; flight operations on most other ships would have been already cancelled or severely restricted due to the very heavy swells.
