It really depends on what you're after, because a rifle and a crossbow solve different problems. A rifle gives you precision at longer distances, faster rate of fire if you need a quick second shot, and recoil management you've already got down after a lifetime. A crossbow is quieter instead (something worth considering in Monferrato where you might have neighbors nearby), requires less physical strength at the moment of the shot, and for medium distances like 30-40 meters it works great. On wild boar, honestly, it depends on your specific territory: if you hunt from blinds where animals might come pretty close, the crossbow could give you that advantage of lower noise. But if you're working more open ground where you need to shoot from 50+ meters out, the rifle still gives you better control and penetration.
What I see is that a lot of people switch to crossbows not because it's "better" in absolute terms, but because it solves certain annoying aspects like noise and resetting your aim between sessions. But if you already know your rifle inside out, you know your gun, you know how it behaves in your area, switching weapons means starting from scratch with practice. Practicality isn't even that different when you're used to something. In my view the real reason to consider making the switch is if your hunting style has changed or if the times in Monferrato now allow better use of the crossbow (certain periods and zones have different regulations). Otherwise, sticking with what you know well is a concrete advantage not worth throwing away.
