Obviously always fly the aeroplane the way your company wants to to. They are paying your wages, after all!
Having said that, an OEI ILS is the same as a 2EO ILS, except the "Straight-In Approach OEI" Checklist in the FCOM/QRH requires you to delay the selection of CONF FULL until you're established on the final approach path.
If you elect to do a CONF 3 landing, CONF 2, then Gear Down, then CONF 3 when established on the final approach path is the orthodox technique. This technique also avoids unneccesary "L/G NOT DOWN" CRC and Master Warning.
