Anyone have success with one interval day and one long ride with intensity?

I've found difficulty recovering from two intensity days plus one long ride per week (and the rest zone 2).

Instead, I've seen more improvement with one intensity day and one long ride the contains some intensity (e.g. including some Tempo, or climbs at threshold in the long ride).

Is this a common/ valid approach? Has anyone had success with it? To maximise gains should I perhaps revert to two intensity plus a long ride and just stick with it until I acclimate?

Many thanks!
