Practical differences
Highlighted cells show a lower reference price, support for more listed speeds, or the presence of a convenience feature. They are not an overall score.
Both are belt-drive, so that part of the experience should feel similar on either deck: a motor that's mechanically isolated from the platter by an elastic belt, which is the usual route to a quieter noise floor — the default choice across most of hi-fi.
The Micro Seiki BL-91 is discontinued, so that side of this comparison is really "used Micro Seiki BL-91 vs new Oracle Delphi" — factor in condition, service history and the lack of a warranty against a fresh unit with manufacturer support.
Bottom line: both are £1,300 at reference price — price doesn't separate them, so the table above is where the real differences show up.
