The barrels of these crack easily. Go with TWSBI.
And if your Safari barrel does crack it still won’t leak ink all over, since the ink is in a cartridge and not directly in the barrel.
The capacity on TWSBIs is great though, my 580 is one of my favorite pens. In the Safari’s price range the Eco is a great pen too.
Nib problems on the other hand, less helpful. A friend bent the tip of his Eco (fell off a table I think) and they said “buy a new pen”. Spares not even for sale.
