I did like the 48-45-34/13-15-17-19-21-24 triple setup I put on the Peugeot PKN-10 before I gave it to my son, who gradually had me change it to 52-45-34/13-15-17-19-21-23-26.
When I was limited to 5 cogs in back, I converted most of my bikes to triples, either as described above or in a third-step format, such as 48-45-42/13-16-19-23-26. With 6 or 7 cogs in back, I find less urgency, but then I do not carry a gear higher than 96 inches (46/13 or 50/14) on my road bikes.
