Shadowrun 5e Aumentation Question

[Anderlith]

In an upcoming shadowrun game my girlfriend wants to create a streetsam, what is the best Initiative/Reaction bonuses she can get starting out? Which are better in the long run?

Wired Reflexes 2 and the adept power (combat reflexes?) are the standard for sammies at chargen and give you 2 extra dice. Auto-injected drugs are very cheap for the effect, but you have to know what you're doing.

You can also go all in with Move By Wire and have ludicrous initiative, even though it eats most of your essence on its own.

The important thing for a sammy is having 3 initiative passes during most combat rounds.

Whatever you do for initiative, it's most likely very expensive and you're not realistically going to upgrade it during play. So make sure that whatever you have at chargen is good.
