Only Maxis can fix this problem. It is because they didn't peer with Equinix SG on IPv6.
Here is how to verify BGP routing...

Refer to Maxis IPv4 peer:
https://bgp.he.net/AS9534#_peers

You can see from your IPv4 traceroute it go from Maxis directly to Equinix SG.

From https://bgp.he.net/AS9534#_peers6 you can see Equinix SG is not peered for IPv6.
Alternatively, you can see the IPv6 don't have "X" under Peer v4.

You then need to check Graph v6: https://bgp.he.net/AS9534#_graph6
Line in BOLD means they are upstream provider.

Maxis has 3 upstream provider: Telecom Italia, NTT, TATA.

So Maxis just dump the packet to one of their upstream, which is NTT.
NTT route the packet to AS3267, which is GTT Communications.
It is not TiNet.

GTT has a public Looking Glass:
https://www.as3257.net/lg/

2001:19f0:fc00::a4f:252 is located in London, so you can choose any LON router, and enter your destination address:
2001:19f0:4400:4001:5400:ff:fe32:b7e5

You can watch your packet traverse their MPLS network.

You can also do the reverse and start from https://bgp.he.net/AS20473#_peers6
You might be wondering if both the source and destination share a common peer, which is NTT, why do the packet need to traverse GTT?

Fortunately, NTT also has a Looking Glass:

If you select BGP and see the prefix announcement, the two network didn't actually connect directly

Looking at this one specific traceroute, TM is better

There are a lot of quirks in traceroute. Someone wrote about it here:
https://gekk.info/articles/traceroute.htm

Remember to read the SlideShare about it too, linked here:
https://www.slideshare.net/RichardSteenberg...with-traceroute

A general question I see people ask before they sign-up is which ISP has better route?
This question don't have an answer. It is like asking which ISP build better roads. There are a lot of different roads in the Internet. Some are better, some are worse. What matter is the road you use often and the time of day you use them.

Even then, road change often with peering, Policy Based Routing, congestion, which may or may not have anything to do with your ISP at all.

I just give a hypothetical example for this specific case:
If Vultr were to be in SGIX instead of Equinix SG, it might work best on Maxis and worst on TM.

Like I pointed out above, the best thing for consumer is for each ISP to have a public Looking Glass portal. This way we can check out how each ISP route before signing up. Gamer will use the Looking Glass to check for their game servers, during the time when they play game.
