Tires to use?

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

There will be no noticeable difference by mm size , only by material and type . depening on internal rim width and tire . a 23 can be a 25 and 28 can be around a 30 ..

2mm means roughly (25/23)^2 -1 = 18% more volume. On top of that with the increased volume and distance from the rim you can run lower pressure, say, 10 or so psi lower. It'll ride a lot smoother.

You won't notice the weight difference between 23s and 25s, but I'm pretty sure you'll feel the difference in reduced road buzz and improved general smoothness. The only downside of switching to 25s for me was that a fully inflated tire wouldn't fit between the brake pads (Campagnolo), but as long as I didn't blow the tire up to full pressure before installing the wheel, there was no problem - just followed a slightly different routine.

If you're racing, it's debatable these days but I'd say the 23's have a very slight margin.

In comfort the 25's have a wide margin.

Your call.

There are a lot of variables. But if Simon Says then it must be true

Just get the 25 and do no over think. The only thing better for climbing is hill repeats and plenty of training, not tires.

Rough country roads (if that's what you mean) = I personally like 700x28s. They're fast enough when it's smooth, but give you confidence when you're forced to hug the junk on the shoulder. Also handy for the occasional unpaved roads you'll come across in a rural area. YMMV.
If you don't have clearance for 28s, then yeah, 700x25 next best thing.

But more seriously it doesn't matter. Tire wear out. You can try 25 next time and if you don't like it go back.

Buy 25s. lower your pressure a little and ride the rubber off of 'em. If you like them, buy more. If you don't, go back to 23s.

Your ideal tire size varies based on your weight. A 130lb rider might be best at 23c while a 200lb rider might be best at 25c or 28c. If you weigh more than the super skinny racers, most likely 25c will always be better for you for everything.

There are tire weight/tire width charts, but those charts assume you're riding on smooth pavement. If your roads are rougher than that wider tires are better.

In the Paris-Roubaix which is a race on rouch cobblestone roads, the winning riders ride 28c-32c because a wider tire is faster on a rougher surface.

The most popular particular brand of tire for road riding with decent flat protection is the continental gp4000. It's a great tire for speed, traction on both dry and wet pavement, and has decent flat protection. Only complaint about it is it the "feel" of the ride, it has a reputation for feeling a bit "dead" (that was my opinion of it so I use a different tire but I'm also riding for leisure so tire feel was a higher priority than people riding for speed).

25mm tires will be more comfortable and stable than 23mm tires, big brands of tires may also reduce wind resistance.
25mm tires are indeed heavier than 23mm tires, but there are more advantages to cover up this shortcoming.
