Yes, absolutely. The key difference is in the incentives/outcomes of the policy. UBI involves lessening incentive to participate in the labor market, lower taxes increases the incentive (because you keep more of your earnings). At some level of 'passive' income it becomes very difficult for a rational person to make the decision to go to work every day.
UBI is one of those ideas that is theoretically awesome but doesn't survive contact with reality, or rather the inevitable flawed humans that administer it.
