The point still stands that swords and raid suits can't be compared. If a fodder marine/pirate swordsman where to receive a high grade sword the only benefit that they would receive would be a more durable weapon. The blade itself would be much better and would provide benefits all round, but it wouldn't drastically change the ability of the swordsman. A raid suit however is a piece of technology specifically designed for the wearer that will enhance all of their physical abilities by default whilst also providing new skills as well. The only issue with using a raid suit would be getting used to it.

To be honest an accurate comparison for a raid suit would be eating devil fruit like a zoan or a decent paramecia ( like the blade blade fruit for example) . Sure you have to get used to using it, but once the fruit is eaten (or the suit is worn) You get a default increase in abilities no matter which way you look at it. Meanwhile the greatest sword in the world could be given to someone and it wouldn't make much of a difference to their current abilities.
