alarm, chronograph, travel time, minute repeater, tourbillon, etc...JLC is the one who is peerless. Just naming the Duometre line which includes a monopusher chronograph with foudroyante function, quantieme moonphase with zero reset function, travel time with capabilities to set the travel time the minute, spherical tourbillon, etc...and all this with 2 separate barrels and power reserves for each of them.
That is just a single line from JLC which Omega has no equivalent.
Again, I love Omega and respect their heritage and history, especially for the Speedmaster and several other references but when it comes to horological prowess, they are not even close to the top.
Don't even get me started with Lange, Vacheron, etc...although I would argue that JLC might be even more capable than these 2 overall π€·ββοΈ
