Are there specific technical considerations that would make it detrimental to put your computer in sleep mode every time?

One other negative point is that the laptop will still be consuming a small amount of battery while in sleep mode.

Hibernation is another other option to consider which would completely power it down - yet still allow you to resume exactly where you were when you hibernated it.

Control Panel -> Power Options -> Change Plan Settings -> Change Advanced Power settings -> Sleep -> Allow hybrid sleep (<-- you could also go into the command prompt and type powercfg -h on)

Once those settings have applied, you can go into Power Buttons and Lid in that same dialog box and set it to Hibernate.

Some system processes and applications end up hogging resources and the only way to release it is to restart.

Sleep is often not well supported amongst drivers, as a result, your computer might be less stable.

For example, my video hang problem seems more likely to occur after a sleep cycle...

In Windows I always prefer to reboot my computer once in a while. Usually after updates...

Remember servers does rarely reboot/shutdown, and they don't have any ill effects of this. Of course some badly designed software or device driver may have a memoryleak that is 'reset' during a reboot, but I guess thats pretty rare for a running system.

Any long term effects that isn't fixed by a reboot is rather unlikely...
