Are these good/worth it for a first road bike?

Giant OCR Zero

46.5 cm frame

700c tires

Good working condition as per the seller

*still waiting to hear as to what the other specific parts are*

260 aud / 180 usd

OR

Specialized Allez

44cm frame

Shimano Claris

Good working condition

370 aud / 255 usd

I am 160cm tall and this will be my 1st time having a road bike and don’t really know what to look for. Judging by the prices, I am assuming these will be at least 10-year old bikes. Are they still worth it or am I better off going for bnew ones.

If bnew, I am looking at the ff which are all similarly priced and similar specs:

– Giant Contend AR 4

– Specialized Allez

– Trek Domane AL Gen 4
