Comparing Two Golgari "Sacrifice Big Things" Commanders

Greetings,

I'm interested in a commander themed on sacrificing big stuff for value. Has anyone had the chance to check out both [[Tom, Bert, and William]] and [[The Gitrog, Ravenous Ride]] ?

I've theorycrafted a bit but haven't had a chance to build either.

Some initial thoughts:

Tom, Bert, and William

Pros:

• [[Greater Good]] like effect in the command zone
• Survives the first creature removal spell and comes back as a harder to destroy artifact
• Sac works at instant speed, so big creatures can block for a turn cycle until they're not needed

Cons:

• Costs mana to activate
• Doesn't accelerate lands, short of discard effects like [[Skirge Familiar]]

The Gitrog, Ravenous Ride

Pros:

• Accelerates lands and card draw
• Hasty
• No mana cost for the sacrifice

Cons:

• More telegraphed, the saddled creature needs to survive through combat damage step
• Centered on a combat damage trigger, you might not always be able to get through

I like the idea of Gitrog, especially the land acceleration but I'm concerned that it'll be a bit of highly-telegraphed a glass cannon. And also that it might feel a bit the same from game to game. It also seems like it would draw a lot of attention to the table.

With Tom, Bert, and William I like their persistence and their ability to serve as a value engine without even needing to attack. I'm not as clear on how it wins, short of drawing a lot and casting more creatures via a Skirge Familiar effect to repeat.

If anyone has live experience with either or both of these, I'd greatly appreciate your thoughts (and deck lists!).
