It's only counterintuitive if you take 3e as cannon, which was only true in 3e. If you take it at face value (the 1e stance) it does what it says on the tin. It gives you the strength of a Hill Giant (other giants are available). So a strength 20 fighter won't get any appreciable benefit. If it was a belt/amulet/wooly sock of Fire Giant strength he would.
Just as a wizard with 20 in won't get any benefit from the item (can't remember which one) that raises your intelligence to 19. Does that mean they shouldn't aspire to it? Someone in the party will appreciate the raise.
Part of this is the design decision that human maximum is 20 in any stat, which in turn is to limit non magical enhanced stat based bonuses to +5. Self gimping your design in the hoipe fo getting hold of something like this in the future seems really daft IMO.
In any case it's a very glass half full look at the situation.
