Welcome to the club! The ZX looks awesome! I very rarely see them 
The XUD is good if you like tinkering and playing around with things yourself, as you can adjust the fuelling and boost manually (mechanical fuel pump and wastegate) to get more power out of it. You can get to 150 very easily with a few choice mods. With a HDi you can get to 160odd with an intercooler, upping the boost and remapping it. The HDi is more economical but can have a few problems in terms of fuelling (pumps can shit themselves) and ECU fault codes, where the XUD has no ECU and every problem you find you can fix with a set of spanners essentially. It's swings and roundabouts really, it just depends what you want out of it!
