For security reasons, it is good to use SUA as a daily work account.
About 80% malware run with the rights higher than standard user:
Malicious code and the Windows integrity mechanism - Securelist
Most Windows vulnerabilities can be mitigated by removing Administrator's rights from the PC's user:

When using SUA (without a pain), some conditions should be fulfilled for daily work applications:
1. They should work as standard user (no UAC prompt when executing, saving config files, etc.).
2. They should autoupdate with higher rights via scheduled task.
3. Alternatively, they should work in AppContainer (Universal Applications from Windows Store).
SUA can work well for anyone, who does not:
- install many programs,
- frequently run programs & tasks, that require Administrative Rights,
- need frequent access to 'Windows' or 'Program Files ...' folders.
I think that most average users can be secure & happy with SUA, with occasional help & guiding from more experienced user. The experienced user, should persuade family members or friends to use SUA, because he/she will have much less work with their computers.
