Questions on Slyths

So I've got a couple of questions about slyths, as I'm deciding on my initial purchases to start out my Dark Eldar.

The party buss is a meme, but do they worth their points for 2-3 of them.
I was thinking of getting them so I could put my forward archon and succubus in a venom with them so I can have my other transports running full squads for the extra weapon options.

Also, are the bases the same as the new medusi for AoS? I was thinking of some conversion options there.

I don't know about 2 or 3, but I like at least one to follow my Djinn blade Archon around to soak up wounds. In general I find them a good addition to keep Archons alive.

I wish they stayed characters, though. Don't bother with court if playing ITC.

I'd say 1-2 tops, ssylth are too expensive to be taking a large number of them.

Ssylth have a 40mm base, not sure if the new medusi AoS models have that base size.

My main list has 3 of them riding in a Venom with my 2 blaster Archons. They always do pretty well even if they spend the whole game just shooting their carbines out of the Venom without ever getting in melee.

When they DO get in melee they're even more fun as long as whatever they're fighting isn't too highly armoured.

Sorry if this is a silly question, but why is it bad to take more than 1-2 Sslyth, but fine to take loads of Grotesques?

Because Grotesques are extremely good, where Sslyths are just medium

grotesques have a better invulm and can be taken in units, gain buffs from the haemi and pfp

Better invuln is a bonus from coven, and the sslyths get useful bonuses from most kabal bonuses (24" assault 3 gun, reroll wounds if 1, etc).
Bonus from haemi is comparable to the bonus from the archons.
Pfp is a bonus. Being a unit is probably a benefit most of the time, though forcing them to fire at each separate model and therefore lose any overkill wounds is annoying.
But overall grots can be taken in enough numbers, then have power multipliers stacked on them. And all their benefits and buffs focus towards one goal (big scary melee brick). 9 of them can does that much better than 3, and extends the buff bubble.
Sslyths are more generalists, decent range, decent melee, decently tough, decent utility benefit. And taking 10 doesn't make them much better at their job than taking 3, and the buff bubble gets harder to effect them all.

I took 2 sslyth in my tournament list and i fund them very usefull, you can use them to block deepstrike, they help archon to stay alive and they are dangerous enough to deal with small unit by themself
