When it comes to crime, the right has two competing interests: the conservative law and order and tough on crime stance, vs the libertarian due process stance.
Conservative justices such as Scalia, frequently bent to the libertarian side. Here is my ranking about the most tough on crime justices.
Tier one:
Alito.
If I remember correctly, Alito never vote in favor of criminals, unless in very clear and unanimous cases (I am even not sure if it really exist). He is not afriad of been the 8:1 solo dissenter, such as in Johnson v. United States (2015).
Rehnquist.
Similar to Alito. Although he sometimes vote for criminals strategically after becoming Chief Justice, most famously in United States v. Morrison. (I don't know any cases that he could be the fifth vote against criminals. Please correct me if I am wrong.)
Burger.
He got nominated for CJ largely because of his strong tough on crime stance. He did voted for criminals in Lockett_v._Ohio, but I guess it was a strategic one -- to assign opinion to himself and write a narrow one. (I have to admitted that I am less familiar with Burger, so please remind me any case that he could be the fifth vote against criminals.)
Tier two:
Thomas.
He did voted for criminals occasionally, such as the most recent BORDEN v. UNITED STATES. But I think these come from his pure originalist approach, other than been libertarian. He almost only agree in judgement but never joined the liberal opinion, as compared to Gorsuch. Besides, he did so with much smaller frequency than Scalia and Gorsuch.
Tier three:
Scalia.
He is definitely a tough on crime person, yet voted many times for criminals, from originalist approach, against vague laws, and in searches, etc.
Gorsuch.
Very similar to Scalia, yet softer on crime in general. It gives me the impression that he is relatively strong in death penalty, but weak in other cases related with criminal procedures.
Roberts.
Conventional conservative and judicial restraint stance on crime. He did voted for criminals occasionally, like in Madison v. Alabama. Comparing to Gorsuch, he is weaker in death penalty but stronger in criminal procedures in general.

He seems to take a middle ground of Gorsuch and Roberts, but we need more data to see. He may be the fifth deciding vote of this case

This is more of a guess as no enough data.
Honorable mention:
Breyer.
He may be the most tough on crime liberal justice, especially in criminal procedure cases.
