An NPD station opened just down the road from work and I see that they sell 100 octane.
Is there any benefit in upgrading from BP Ultimate I use at the moment?
100 Octane
Only you can answer that, it will be a price based thing, you probably wont notice a big difference in performance 98 to 100, all else being equal. My understanding is that generally in modern road cars with Lambda sensors etc that going up in octane won't harm your engine and may give it some better characteristics. The same does not apply in reverse, do not go down in octane below what the engine is designed for!
Probably not much help but your simple question unfortunately does not have a simple answer, there are too many variables in fuel sourced from different suppliers, particularly fuel direct from overseas refineries.

Bronzee old age must be setting in, you said this a mere 10 years ago
Use unleaded premium gas with octane of at least 95 (RON) octane.
If premium gas not available, 91 maybe temporarily used, but only under following precautions:
* Only partially filled with 91 & fill up with full grade (ie 98 ) as soon as possible.
* Avoid full throttle driving & abrupt applications of the go faster pedal.
For maximum vehicle performance, use of premium gas is recommended.
