I would imagine these new -10s will be part of a rigorous programme to replace the oldest 738s and also to aid expansion. I think the A320s have enabled Ryanair to step in to the breach to pick up type rates crew from other airlines like at Stansted where Lauda since the pandemic have a pool of ex easyJet STN crew including A320 type rates pilots. I flew Lauda and thought it was great, so much so I'd probably choose a Lauda operated flight where there is a choice, e.g. DUB/STN or NOC/STN.
