I never liked the Intermatic in wall timmers. I have had a ton of failures with those in the past. After 6 months they would die. You get it warrantied but still waisted time. It dies again but that model is no longer available. The Intermatic rep says they had a problem with those but it's fixed withthis new model, And gives you some free ones. I sould have thrown them out but instead I sold them installed. When they failed I had to buy and install another set. Inside some had a micro switch, some plastic gears, and a motor about the size of an eracer. I would guess Intermatic had about 100 different modeles of inwall timmers in the last 15 years. I can't say if they were all bad. I can say many of them had a different programming procedure that I could never learn. Call backs because the timmer was programed wrong are bad. But it is easy to do with some of those models, especially if you have no instructions. Also some use a battery that people don't know about, causing some issues. Or the timmer needs the lightbulb to complete the timmer circuit. Trouble is they don't notice the bulb is out, they just see the bulb is not working. Easy money I guess.
I sold many of the Leviton LCD timmers. Great product. Easy to program once you understand. It is still hard for customers to learn to program and hard for some to see the display.
No experiance with swaylight but they look simple enough. For years I would say I don't know why they don't set up a timmer to program like an alarm clock. Most of the timmers have way too many features that are never used.
