Bolivar, here is my experience.
Our town has 3 Presbyterian or Reformed congregations. (2 PCC & 1 ARP, total pop. 145k)
The use of Presbyterian or Reformed as you indicated in you OP pre-supposed that people know what those terms mean. In my context they do not know this. The question assumes that the name will attract people based on their pre-association with the name. This is a false assumption, in my opinion.
We call our church Redeemer Community Church because our first choice was taken. We wanted to be known as Christ the Redeemer, but the Sunday after we voted to adopt this name a (continuing) Anglican church plant launched with that name. We backed up & picked the closest name that we could.
In practice it matters not at all. This past Lords Day we had 15 or so visiters. 10 were first or second time visitors & more than half were non-christians. Not one of them came because of our name. All came because they were invited (often repeatedly) by people that they knew.
If the goal of your church plant is to preach the gospel to the lost, then pick a name that works in your context. If however your goal is to advance a sectarian agenda then chose your name according to the values of your faction. I am not kidding. Some have declined to support us (financialy) or even pray for us(!) because we do not make opposition to the "Federal Vision" or "EP" the focus of our ministry. For sectarians such as these, the purpose of planting a church is to gain votes at GA. If this type of person is the main source of your support, then learn to live on a lot less money, or adapt you mission to a model that they approve of.
In my humble opinion the point of planting a church is to reach the lost with the good news of Jesus Christ, and NOT to add one more vote to "our" side at GA. This may sound like a rabbit trail, but it is an important part of the decision of what to call your church.
