Like in any competition, that depends on who is there.
For what its worth, squat and DL are very close to my first competition third attempts; bench is higher by about 50 lbs than my current max, all in the 198s. Certainly strong enough to get up on the platform and pretty decent for a first meet all things considered. I know of guys who've put up more at that weight for a first meet and who've put up less too. It doesn't matter. The main thing is going out there and doing it. It's a blast.
As to which seems to be your strongest lift, they seem very balanced. Certainly way more balanced than mine (currently 474/250/529 at about 205). Do you squat wrapped or unwrapped? If unwrapped, I'd say your squat may be your strongest, or your bench. Also, what were they 6/12 months ago? IMO your strongest would probably progress the fastest at first.
