For the M272 engine which is what is in the 2011 E-350, the NGK 4288 Laser Platinum were pretty popular in the W211 forums. The 2012+ had a different engine and used a multi spark system and I believe the plugs were also indexed based on the manufacturer so for those years I'd stick to the oem brand.
For fun, you could try the Autolite Iridium plugs, they're $4.67 per plug on rockauto and there's a $3 rebate per plug so $1.67 a plug or about $10 for a set of plugs or $8.62 if you use the 5% discount code on retailmenot.

So we have have to change spark plug every 60k miles?
I'm surprise we have to change it out that often but if it's called out then I guess we have to do it.
I thought spark plug usually last until 105k miles.

They probably do last for 100k, but that would probably be in 10 years and MB likes to be conservative so there's a possibility that if you leave them in that long, they might rust up or seize and it'd be hard to get them out at that point, easier to just replace them every 6 years. At least it's just a single spark plug, in the older models, they had two spark plugs per cylinder.

Changed them out though as you cannot see internals of the plugs.
