Up here in NW Wa. State, there are quite a few Globals around. Also Dynamos, Valleys, Irving Kayes, Imperials, Qualities, American Games, Brunswicks, etc. -- you get the idea.
Of all the above listed tables, considering ONLY the coin-op type you find in bars (which is what I think you're asking about), in terms of tough construction, set-up, playability and all-round long-lasting and dependable consistency, equally at the TOP OF THE LIST are the Valleys (and NOT the Dynamos!), Brunswicks and Globals. Next best table (very small step down) would be the Irving Kaye. The Globals' pockets seem to play slightly tighter than the Valleys and Brunswicks.
If you think you're looking at a good deal on a Global, TAKE IT!!!
P.S. -- never seen a Diamond, yet -- we're too poor up here
