I'd opt for him out of those three too. Here are some stats.
Deletraz qualified 25th for his debut at Adelaide in 1994. His qualifying time was 2.3 seconds slower than that set by his team mate (Hideki Noda, who was a mediocre pay driver himself). He was 6.2 seconds off pole, which, given he was driving a Larrousse that was normally around 2.5-3 seconds off the pace of the front runners, was not flattering to him. He spent most of the race running in penultimate or last position before eventually retiring with gearbox failure after 56 laps. I suppose it could be argued that he didn't crash, but the counter argument would be that he wasn't going anywhere near fast enough to make a mistake.
1995 was even worse. At the 1995 Portuguese Grand Prix, he qualified the Pacific 24th and last, 14 seconds from pole, and six seconds slower than his team mate (Andrea Montermini). He was lapped twice inside 14 laps in the race before retiring with cramp. At the European Grand Prix he qualified 24th and last again, nine seconds from pole and three seconds slower than Montermini. He finished 15th and last seven laps behind and demonstrated some curious race craft, as this video shows:
