Spinner luggage is more susceptible to breakage because the wheels move in different directions. This is especially true when you're rolling over uneven surfaces like cobblestone. The wheels on upright luggage, on the other hand, tend to be more durable because they don't move around as much.
It is always easier to roll than to slide a body over another. That is the reason it is convenient to pull the suitcases fitted with rollers and is easier to pull a suitcase having wheels because the ball bearings roll and reduce the friction. As Rolling reduces Friction.
Soft-shell luggage, while similar in external size to hard-shell luggage, can frequently offer slightly more internal storage space (as long as inline wheels and not spinners are part of its features).
For those not familiar with the terminology, a spinner suitcase is an upright bag with four wheels (as opposed to roller luggage, which has only two wheels). While it's absolutely not always the case, spinner suitcases are often hard-sided, while roller bags are more often soft-sided.
Rolling your clothes in your suitcase will generally save space. This is because it squeezes air from between folds and means the most of available space is used. If done correctly, rolling can also ensure less wrinkles in your clothes.
In a two-wheel design, the wheels tend to be larger than the wheels on 4-wheel models, so they roll forward in a straight line better than 4-wheeled bags, thanks to the sheer physics of their size. If speed is your highest priority, choose a 2-wheeled bag.
Of course you can — but whether it's a good idea or not is another question. You'd probably need to replace all four wheels — and whether you can purchase suitable ones is questionable.
