If I use the 8610, will I avoid thermal crosstalk in my META42?

Is one solution better than the other?

The current draw should be low enough that thermal crosstalk will not be an issue. The price of either solution is the same. It should not matter much which you choose, but I would go with the AD8610 on the general principle that an opamp per channel is better than using a dual chip.
