question about upgrading OMB 5E stylus

Hello. I'm about to upgrade the stylus on my project debut turntable.

On my visit to the local hifi dealer they adviced me a OM 20 stylus. They told me it would fit on the OM 5's cartridge.

I placed the order for the new stylus but I'm still wondering if the cartridges of the OM 20 and the OMB 5E are the same. I was thinking that the OM 20 comes with a better quality cartridge. I do believe the new stylus will fit, but it's hard to believe that this better stylus uses exactly the same cartrigde.

The store orders the stylus on thursday, so I still have some time to order a complete cartridge, and cancel the stylus.

Thanks in advance for all the help.
