> In that case encoding speed doesn't matter much

When occasionally encoding: yes. When your daily business is encoding larger batches: not necessarily.

edit: Just to clarify: we've got an encoding farm which will have to be siginficantly expanded if a substantial amount of content will have to be transcoded in H.265.

And if you need to have a h.264 fallback anyway, then any alternative codec starts at a disadvantage, as it can only have marginal gains in return for the extra encoding.
