Either is fine and it depends more on how you use it. Typically folks sensitive to harsh vapor do more of their vaping with water. Mouth pulling with any vapcap also helps cool the vapor considerably.
You'd probably do well with a Splinter and XL8R stem or even the humongous Drydrotube contraption if the awkward size isn't an issue.
The splinter advantage is that you control specific settings in addition to what stems or bubbler you might use. So you can run a Splinter with a cooling stem just normally in wattage mode with no fancy settings and if the vapor is harsh you can lower the wattage or tweak the resistance down slightly to tame the beast.
With any vapcap you'd probably just want to use a single or double torch instead of a triple or quad. And again a vong in a bubbler even dry will add a lot of cooling.
