i'd land with whatever gear you have if its a hard surface in a slower airplane.. you can balance it on one wheel til your just about stopped.. if your careful.
Seen an uneventful 2 wheel landing in duchess in person.. and seen videos of others on just the nosewheel or just 1 main.. they just balanced on the wheel for as long as possible..
but.. I fly a pitts and land on one wheel all the time for fun.. so..
In the Embraer though.. Two mains.. definitely down. Any thing other than that Id probably put em up.. I think thats what the manual says as well..
Here is a pic of one of our jets in Boston.. pilots had a 3 green down indication, shortly before touchdown got a "landing lever disagree" warning, they said they thought gear was down and continued, can't remember all the details of exactly why they continued.. but anyway for whatever reason they continued the approach.. note the gear doors open, felt the sink more than normal at touchdown, realized gear was NOT down.. MAX thrust.. airplane dragged the flaps then took off again, got the gear down manually, landed safely without incident.. VERY, VERY lucky on that one. Only damage was on the flaps.. They tested it on the ground on jacks, the plane showed 3 green down and locked, and the gear did not come down.. they put that same control module in another aircraft and duplicated the problem.. turned out to be a faulty computer control module embraer had to fix..
