I sense troll vibes. Experienced pilots don’t ask these questions.

Troll vibes? I never flew widebody so what is exactly the troll part in my question? Or maybe you actually are one of those guys that knows everything from the sefond you were born?

Unless you like long term training, get on the plane you are most likely to upgrade on down the road. Its also better to have right seat time before upgrade (for those who just like to argue, I said better, not necessary). Choose based on schedule, QOL, commutability, etc., not “flying the 74 would be cool and boost the ego.”

But it is cool, and it does boost the ego.

Well, OP does say they’re from Europe and they haven’t flown very much...

Well…

If he really is that new to flying staying on his current airframe and focusing on general experience and airmanship would be my recommendation.

Some errors in translation it looks like.
I’ll try and answer for a European perspective.
Aviation tends to be very siloed, once you’re on a Boeing or an Airbus you tend to stay on it for the majority of your career as job opportunities generally require a type rating of either manufacturer.
So in the big scheme of things, if you can switch to an Airbus type without cost to you then take it.
Future employment opportunities in/outside of Europe may depend on it.
Go for the A…

How does it boost your ego? Do you need to buy larger, roomier boxers after flying it?

Yes and my watch grows two sizes.

Don’t forget a 4th bag full of espresso machine and bean grinder parts. The 3rd bag was for their special pillow.
