Easier to play than what?
First off, your classical guitar IS an acoustic guitar — you don’t have to plug it into an amp to get sound out of it. The difference between your “classical” guitar and an “acoustic guitar” is that the classical one has nylon strings for a mellow, sweet tone suitable for classical music and some jazz, whereas the “acoustic guitar” has steel strings on it for a brighter, crisper tone more suitable for country, rock, blues, folk, bluegrass, etc. The classical guitar is also built out of much lighter woods and different internal bracing, to be as responsive as possible to the lightweight nylon strings. On the other hand, a steel-string guitar is built of much heavier woods and heavier bracing to withstand the much greater tension of steel strings. All this means that if you try to put steel strings on your classical guitar, you will very quickly wind up with a BROKEN instrument, as the steel strings will quickly warp the neck, pull the bridge off, and/or buckle the top. DON’T PUT STEEL STRINGS ON A GUITAR BUILT FOR NYLON STRINGS! EVER!
Secondly, the neck and fretboard on a classical guitar is generally WIDER than on a steel string acoustic. Not sure why you think an acoustic guitar necessarily has a thicker neck, or why you think that a thicker neck would be “easier” to play???? Different makes and models of acoustic guitars have different neck profiles — some thinner, some thicker — and its a matter of individual taste as to which ones are easier to play.
And I don’t know why you think chords would be “easier to catch” on an acoustic, except that, as I said, classical guitars have wider fretboards than steel string acoustics. But steel string acoustics tend to have higher action and heavier strings than electric guitars, so its actually harder to play an acoustic than it is to play electric.
Bottom line is that, the classical and electric guitars you already have can (and should) be set up by a good guitar repair person to be as easy to play as possible. So more than anything else, its a matter of SOUND. If you’re interested in playing acoustic rock, country, blues, folk, or bluegrass, then you’ve probably already figured out that you can’t get the right guitar sound from either your nylon-string classical or your electric, and you need a steel string acoustic. In which case, your next step would be to go to a good, well-stocked guitar shop, and try out a bunch of different steel-string guitars for yourself to figure out what neck profile, fingerboard width, and body size feels most comfortable for YOU to hold and play, and which instrument has the SOUND you love best. That’s the guitar you’ll want to buy.
