Larger companies tend to prefer weekly/biweekly as you don't get that month-length variance. On the other hand, many employees don't like it as much because their biggest bills tend to be paid monthly so they'd prefer their paychecks to be aligned.
I've seen both and as an employee the semi-monthly is the best - it's about biweekly but you don't have to wonder why some months you only see 2 paycheck vs. 3. Predictable is really good.
From a company standpoint, not having to accrue the liability on the ledger simplifies the accounting auditability & ability to close your books monthly.
I've had it both ways, and prefer it biweekly. That way, I can build my budget based on 2 pay periods, and have the occasional 3rd paycheck in a month go immediately toward savings.
I've had it biweekly including in my first "tech" job. I made enough that paying bills wasn't really an issue and having the "extra" paycheck for savings seemed almost like free money towards savings/paying off loans.
On the other hand, I understand people who are on tighter budgets who would rather have their revenue better aligned with their expenses rather than having to balance them on their own.
